Xiamen Bridge

Xiamen bridge is the first highway bridge across the Strait in China. It is composed of main bridge, Jimei overpass, Gaoqi approach road and automatic control system. It was built on October 1, 1987 and opened to traffic in May 1991. Jiang Zemin, general secretary of the CPC Central Committee and President of the people's Republic of China, personally inscribed "Xiamen bridge" and cut the ribbon for the formal opening of Xiamen bridge on December 19, 1991. The main bridge is 2070m long and 23.5m wide. The straight through Jimei interchange consists of seven ramp bridges. Gaoqi approach road is 855m long and 23.5m wide, which is the standard of first-class highway.

Xiamen Bridge

Xiamen bridge is a sea crossing bridge connecting Huli district and Jimei District in Xiamen City, Fujian Province, China. It is located on the Gaoji Strait of Xiamen and is one of the important passageways for Xiamen to enter and leave the island.

The construction of Xiamen bridge started in October 1987 and was completed and opened to traffic on December 19, 1991.

Xiamen bridge starts from Jiahe Road, Huli District, Xiamen City in the south, and ends at Jimei interchange, Jimei District, Xiamen City in the north. The total length of the line is 6.695 km, and the total length of the main bridge is 2.07 km. The bridge deck is a two-way four lane urban trunk road with a design speed of 60 km / h. The total investment of the project is 156 million yuan.

Construction process

In September 1984, Xiamen municipal government held a meeting in Jimei to collect the design scheme of Gaoji Strait Bridge.

On December 2, 1986, the former Ministry of communications of the people's Republic of China approved the design specification of Xiamen Gaoji Strait Bridge.

On March 9, 1987, the former Ministry of communications of the people's Republic of China approved the preliminary design of Xiamen Gaoji Strait Bridge with an investment of 85.54 million yuan.

In October, the construction of Gaoji Strait Bridge started.

In April 1991, Gaoji Strait Bridge was completed and named Xiamen bridge. On May 1, Xiamen bridge was put into trial operation. On December 19, Xiamen bridge was officially opened to traffic. Jiang Zemin, then general secretary of the CPC Central Committee and chairman of the Central Military Commission, cut ribbon for the opening of Xiamen bridge and inscribed the name of "Xiamen bridge".

On January 31, 2019, the limited speed of the main bridge of Xiamen bridge will be increased to 90 km / h.

Bridge location

Xiamen bridge is located between Gaoqi, Huli District, Xiamen City, Fujian Province, and Jimeixue village, Jimei District, Xiamen City, China. It spans the Gaoji Strait in Xiamen, about 7.6km away from Haicang Bridge, about 600m away from Xinglin bridge, and about 3.1km away from Jimei bridge. Xiamen bridge starts from Gaoqi, Jiahe Road, Huli District in the south, crosses Gaoji Strait in the top, reaches Jimei interchange in Jimei District in the north, connects Yinjiang road and Tianji connecting line of Xiamen Sha expressway, and has ramp to Jixing seawall.

Architectural design

building structure

Xiamen bridge is composed of Gaoqi approach road, main bridge, Jimei interchange and ancillary works. Xiamen bridge is a super large bridge of high-grade highway with two-way four lane and pedestrian road, which has the function of urban bridge.

The main bridge of Xiamen bridge is a five span prestressed concrete continuous box girder rigid frame bridge with equal span. The superstructure is a continuous box girder with span. The domestic QM system and VSL system are used for prestressing. The transverse direction is two independent single box median strips. The substructure is rectangular pier. Jimei interchange is a large-scale interchange. The superstructure of approach bridge is PC hollow continuous slab. Domestic QM system is adopted for prestressing. Ramp bridge is RC hollow continuous slab. The substructure is single column or double column pier, the foundation is expanded foundation and bored pile, and the abutment is U-shaped.

Design parameters

The Xiamen bridge is 6.695km long, of which the bridge project is 2.07km long, the deck is 23.5m wide and 3M high. The design capacity of Xiamen bridge is 25000 vehicles / day, the design speed is 80 km / h, the design service life is 100 years, and the design load is car class 20, trailer class 120 and crowd 3.5 kn / m2.

The length of Gaoqi approach road of Xiamen bridge is 855m, which is designed as the standard of first-class highway, and the pavement width is 23.5m.

The main bridge of Xiamen bridge adopts the structural system of (46 × 45) m five joint equal span prestressed concrete continuous box girder rigid frame bridge, with a total length of 2.07 km. The upper cross section is arranged as follows: 1.5m (sidewalk) + 9.5m (motorway) + 1m (median) + 9.5m (motorway) + 1.5m (sidewalk), with a total width of 23.5m, and two independent single box median strips. The main foundation type of the lower rectangular pier is 150 cm diameter bored pile, and the other 13 are driven PC square pile and 2 expanded foundation.

Jimei overpass of Xiamen bridge is composed of approach bridge, 6 ramp bridges and 7 approach roads, with a total length of 3.77 km, of which the bridge length is 2.482 km and the approach road length is 1.288 km.

Operation

Ticket price

Xiamen municipal government issued a circular on April 29, 2019, announcing that from 0:00 on May 1, 2019, it will stop collecting vehicle tolls for "four bridges and one tunnel" in Xiamen, including Xiamen bridge.

Traffic matters

Xiamen bridge is located in the southeast coastal area of China, which is vulnerable to typhoon weather. According to the "emergency plan for flood control and typhoon prevention in Xiamen City" issued by Xiamen municipal government on April 14, 2014, when the measured wind force reaches level 10, Xiamen bridge will be temporarily closed and vehicles will not be allowed to pass.

traffic flow

In 2019, the average daily traffic flow of Xiamen bridge into and out of the island is 797600 vehicles.

Construction achievements

Technical problems

For the first time in China, the construction technology of longitudinal sliding film hole by hole cast-in-place concrete and QML type prestressed steel strand connector are adopted for the upper box girder of Xiamen bridge. The application of the two methods avoids the complex structure of the protruding "toothed plate" structure and the prestressed tendon connection and distribution inside the box girder, makes the beam span concrete have good integrity and high quality, increases the corrosion resistance and durability of the structure, and makes the construction safe and fast.

Honorary recognition

From 1991 to 1994, Xiamen bridge project successively won Xiamen quality engineering "Egret Cup" award, Xiamen science and technology progress first prize, Fujian Province Quality Engineering Award, Ministry of Communications Science and technology progress third prize, Ministry of Construction Quality Model Engineering Award, Ministry of Communications "Eighth Five Year" ten highway engineering title and China Construction Engineering Luban Award.

Construction planning

On January 23, 2020, Xiamen municipal government announced the list of key projects and annual investment plan of Xiamen City in 2020, including Xiamen bridge reconstruction project. In order to improve the traffic capacity of Xiamen bridge, Xiamen bridge will be reconstructed and reinforced in 2020, using sidewalks and isolation belts to transform two-way four lane into two-way six lane.

Value significance

The completion of the Xiamen bridge has improved the difficulty of getting in and out of Xiamen Island, strengthened the links between Xiamen City and other regions outside the island and within the province, and further enhanced the development potential of Xiamen Special Economic Zone. < I (review of Xiamen Road and Bridge Construction Group) < / I
