Shanghai Xupu Bridge

Xupu Bridge is the river crossing point at the south end of Shanghai outer ring road. It is the traffic hub directly connecting Shanghai Nanjing and Shanghai Hangzhou expressways into Shanghai river crossing. It is also the most convenient connecting channel between Hongqiao Airport and Pudong International Airport. Xupu Bridge is another cable-stayed bridge connecting the two banks of Pujiang River in the south of Shanghai. The main bridge is 1072m long and 35.95m wide, with two-way 8 lanes. The main tower is in "a" shape, 217 meters high, and the cables are arranged in a fan-shaped plane, with a total of 30 pairs of 240 cables.

Yangpu, Nanpu and the four Huangpu River bridges, Xupu and Fengpu, built later, have laid the foundation for the development and opening of Pudong and the linkage development of Pudong and Puxi.

Construction process

In March 1994, the preliminary design of Xupu Bridge was completed; in April of the same year, the construction of Xupu Bridge began.

In December 1996, the closure of the main girder of Xupu Bridge was completed.

On June 24, 1997, the opening ceremony of Xupu Bridge was held.

On September 2, 1998, Xupu Bridge passed the national acceptance.

On December 31, 2007, the vehicles of dangerous chemicals crossing the river were transferred to Xupu Bridge.

In July 2018, in order to welcome China International Import Expo, Xupu Bridge was painted.

Bridge location

Xupu Bridge is an integral part of Shanghai Outer Ring Expressway < I (Shanghai Expressway S20) < / I, which is located in the southwest of Shanghai. It starts from Longwu Road Interchange in the west, crosses Huangpu River Waterway in the upper part, and ends at Jiyang overpass in the East. It is 9km away from upstream Minpu Bridge in the South and 10.2km away from downstream Nanpu Bridge in the north. The main axis of the bridge is located in the center of chedu ferry of original Sanpu line, and the approach bridge of Puxi section connects Longhua township of Xuhui District, The approach bridge of Pudong section connects Sanlin Township.

Architectural design

building structure

Overall layout

Xupu Bridge is composed of water main bridge, land Pudong bridge, Puxi approach bridge, A-shaped bridge tower and its interchange ramp. The main bridge section is arranged from due west to due east.

 

Design concept

The architectural color of Xupu Bridge is mainly bright. The overall architectural style of Xupu Bridge is different from that of Nanpu Bridge and Yangpu Bridge. Under the condition of meeting the structural stress, functional requirements, simple structure and convenient construction, the new tower type, cable surface type and architectural color are selected to form a new style and coordinate with the surrounding environment.

 

Design features

Xupu Bridge is the third super large bridge across Huangpu River in Shanghai. The main bridge is a cable-stayed bridge structure with double pylons, double cable planes, side span concrete beam and mid span steel concrete composite beam. The main beam can move freely in longitudinal direction, with limit and anti-seismic devices in transverse direction. The simply supported T-beam of side crossing hole is supported on the side pier and end beam at the end of side span of cable-stayed bridge. The main tower is A-shaped and the foundation is Φ 900 The steel pipe pile takes gray gravel medium fine sand or gray powder fine sand as the bearing layer; the two steel main beams are H-shaped, and the steel beams are spliced on site with high-strength bolts; the bridge deck is made of C60 concrete, and longitudinal joints are set in the bridge deck The cable is arranged on a spatial fan-shaped cable plane; the shore span is prestressed concrete beam; the middle beam is I-shaped; the side span beam is provided with longitudinal and transverse prestressed steel tendons; the steel hinge line and corresponding supporting anchorage devices are selected; the transition hole is prefabricated T-shaped simply supported beam.

 

Design parameters

The Xupu Bridge is 6017m long and the main bridge is 1070m long. The span layout of "40m (transition hole) + 40m + 3x39m + 45m + 590m (middle span) + 45m + 3x39m + 40m + 40m (transition hole)" is adopted. A vertical curve with a radius of 12000m is set in the middle. The longitudinal slope of the bridge deck is 3.5% and the transverse slope of the bridge deck is 2%. The width of the bridge deck is 35.95m and the total width of the transition hole is 33.95m. The height of the main tower is 221m and the section size is along the bridge The bridge is 13.0 to 9.0 meters long in the direction, 9.3 to 5.0 meters wide in the transverse direction, and 0.0 to 1.6 meters thick in the wall. There are 240 stay cables in the whole bridge, and the standard cable distance on the beam is 9.0 meters for the middle span, 6.5 meters for the side span, and 2.1 meters for the cable distance on the tower. The main section of the bridge is a two-way eight Lane urban expressway, which adopts the first-class highway standard.

 

 

Equipment and facilities

Electronic monitoring

As of September 2017, the whole section of Xupu Bridge has been equipped with traffic monitoring equipment such as electronic police; meanwhile, the non-stop pre check weighing system has been built at the overload control station of the bridge.

 

Lighting facilities

On October 3, 2018, in the theme lighting show of "I love you China" in Shanghai, Xupu Bridge set up lighting facilities with blue and white as the keynote to show the Shanghai style of water charm.

 

Operation

Traffic matters

As of December 22, 2007, the weight limit of Xupu Bridge is 55 tons, the width limit is vehicle width + 0.2 meters, the height limit is 4.2 meters, and the length limit is car length + 2 meters.

 

Construction achievements

construction technology

The side span of Xupu Bridge adopts reinforced concrete structure, and each span is connected by 18 precast I-beams through cast-in-place joint concrete to form a multi chamber single box section. The fabrication and hoisting of precast beams are the same as the construction technology and method of approach bridge prefabrication, and the same set of beam fabrication, hoisting technology and beam erection construction equipment can be fully used to complete the construction of side span and approach bridge. During the construction, the side span is constructed in parallel with the main tower This is one of the advantages of hybrid cable-stayed bridge, which can reduce the construction period and project cost.

 

Scientific research achievements

Cultural characteristics

scenic spot

In March 2019, Shanghai Pujiang "fast tour line" opened for trial operation, and Xupu Bridge belongs to the "elite Tour" of Pujiang.

 

Value significance

Xupu Bridge is another important infrastructure for the development and opening up of Pudong and the revitalization of Shanghai. It is a traffic hub directly connecting Shanghai Nanjing Expressway and Shanghai Hangzhou Ningbo Expressway into Shanghai. It is also the most convenient and fastest connecting channel between Hongqiao Airport and Pudong International Airport. Its completion marks a new level of bridge construction in Shanghai and makes Shanghai an international metropolis New landscape and wind color. < I (review of Shanghai Construction Forum) < / I
