Architectural design

building structure

Overall layout

Xinglin bridge is composed of main girder of highway bridge, main girder of railway bridge, approach bridges on both banks, railway tracks, piers and their interchange ramps. The main bridge section is arranged from northwest to Southeast.

 

　　

Design features

Xinglin bridge is designed with constant height continuous prestressed concrete box girder. The bridge deck of the upper structure is divided into several sections, symmetrical along the bridge center line, the main beam adopts single box single chamber section, and the style of the main beam of the whole bridge is unified; the cross box beam of the lower structure adopts C50 concrete, the top and bottom plates adopt vertical and horizontal two-way prestressed system; the bearing platform adopts C45 high-performance concrete. Pier adopts slab pier, pile foundation adopts bored pile, and pier body adopts C40 concrete.

Design parameters

The total length of Xinglin bridge is 8.53km, with the span arrangement of (5 × 32.7m) + 8 × (8 × 32.7m) + 3 × (8 × 50.3) + 2 × (5 × 32.7m) + 10.608m. The bridge deck is composed of three parts, the clear distance is 1m, the width of single deck is 15.5m, the one-way cross slope is 2%, the cantilever arm length of main girder is 4.9M; the height of 50.3m span box girder is 3.0m, the thickness of top slab is 26cm, the thickness of bottom slab is 26cm, the thickness of fulcrum bottom slab is 40cm, the thickness of middle span web is 55cm, and the thickness of Web slab is 80cm within 9.5m from fulcrum. 32.7m span box girder, 2.0m high. The size of top, bottom and cantilever is the same as that of 50.3m span box girder. The thickness of the web in the middle of the span is 50 cm, and the thickness of the web within 4.5 m from the fulcrum section is 75 cm.

 

Equipment and facilities

lighting

On August 30, 2008, the lights of the whole Xinglin bridge were on, and several long pole street lights were installed on the road surface of the bridge to facilitate the traffic at night.

 

viewing platform

At the peak of "m" bridge deck, Xinglin bridge is equipped with two viewing platforms. The viewing platform will be separated from the driveway to form an independent area, which can not only provide people with a place to rest and watch the beautiful scenery of Xiamen, but also play a role of guiding platform in case of accidents on the bridge surface.

 

monitoring system

As of August 2010, Xiamen public security traffic administration has added 6 sets of automatic capture devices for speeding and 6 sets of automatic capture devices for lane changing in the "two bridges and one tunnel", a total of 12 sets of monitoring systems, including the "two bridges" including the Xinglin bridge.

 

Operation

Fare system

From May 1, 2019, Xiamen Municipal People's government will stop collecting vehicle tolls for "four bridges and one tunnel" in Xiamen, and Xinglin bridge includes "four bridges".

 

Traffic matters

On September 1, 2008, Xinglin bridge was opened to traffic with a speed limit of 80 km / h. motorcycles, pedestrians and non motor vehicles are prohibited on the bridge (freight vehicles can pass).

 

Construction achievements

Technical problems

The mss50 / 1800 movable formwork is adopted for Xinglin bridge, and the high-altitude backward dismantling process is adopted to remove the movable wooden frame. In order to reduce the anchorage weight, reduce the number of anchorage points, avoid multiple transfer of demolition equipment, improve the demolition efficiency and save the demolition cost, the high-altitude backward moving ladder demolition process is adopted, in which the mobile wooden frame is first removed from the outer formwork and the rear guide beam, and then the mobile wooden frame is moved backward, and the main beam is removed from the rear section by section.

Value significance

Xinglin bridge connects Chenggong avenue to the East and Dongdu road to the south, which plays a very important role in speeding up the traffic speed inside and outside the island and implementing the "half an hour" traffic economic circle. After the bridge is opened to traffic, on the one hand, it reduces the traffic pressure of the north passage, on the other hand, it also greatly reduces the distance and driving time from outside the island to the airport, ferry and Dongdu port area, and the port logistics, commerce and trade are also improved Development, finance and insurance, tourism exhibition will better serve the whole Haixi Economic Zone and give full play to the regional leading role of Xiamen Special Economic Zone. < I (Xiamen Municipal People's Government)
