1、 Project overview (I). Project introduction This project is the xx branch line project of xx expressway in xx city. It is an important part of xx city's road network and a key construction project in xx city. The project is located in the southeast of xx city. The route is roughly south-north, starting from xx in the south. Along the planned Wutong Mountain Avenue, it runs northwest through Yantian and Zhengkeng tunnels, crosses Wutong Mountain, passes the west side of Xikeng, crosses 205 National Highway, the west side of Shenkeng Village, and crosses Shuiguan Expressway, and ends at Paibang Flyover of xx Highway in the north, connecting with the planned Dongguan Boshen Expressway. The contract section is composed of two bridges, namely XX Bridge and Liantang Viaduct. The bridge site of xx Bridge is located between K9+168 and K9+298 of xx branch line of xx Expressway. The general layout of the bridge opening is 4 × 30m box girder structure, and the superstructure is fabricated prestressed concrete continuous box girder. The total length of the whole bridge is 130.648m. The substructure adopts column pier, rib abutment and column abutment; The foundation is pile foundation. The transverse bridge deck of the bridge is 32m wide and divided into two parts, the left part is 128.193m long and the right part is 130.648m long. Liantang viaduct is located between K9+713-K10+151 of xx branch line of xx expressway. The general layout of the bridge opening is 14 × 30m box girder structure, and the superstructure is fabricated prestressed concrete continuous box girder. The total length of the bridge is 437.395m. The substructure adopts column pier and rib abutment; The foundation is pile foundation. The transverse bridge deck of the bridge is 32m wide and divided into two parts, the left part is 437.395m long and the right part is 428.203m long. The whole bridge of xx Bridge is located on the circular curve with R=800 m, while Liantang Viaduct K9+722 to K9+810 is located on the transition curve, and K9+810 ～ K10+151 is located on the circular curve with R=750 m. The superstructure beams of the two bridges in the contract section are 30m post tensioned prestressed concrete continuous box girders. The bridge is divided into two pairs horizontally, and five pieces are arranged in a single transverse direction. The top plate of the box girder is 17-25 cm thick, the web is 18 cm thick, and the bottom plate is also 18 cm thick. A fillet section with R=5 cm is set at the junction of the web and the bottom plate. Due to the demand of route alignment, 2% single slope is set at the top of precast box girder, and the height of box girder is about 1.60m; The cantilever length of side span side beam is about 1m, and that of mid span cantilever is about 80cm; For this reason, the thickness of the cantilever varies with the different positions where the box girder is used, with the thickest part being 27cm and the thinnest part being 18cm; Post tensioning construction of prestressed steel tendons shall be arranged in the longitudinal positive bending moment and negative bending moment sections respectively to meet the requirements of structural stress. The lower structure of the bridge is also symmetrically arranged in two pieces. The bent cap is a cantilever double column pier frame, which is an ordinary reinforced concrete structure. Pier columns with diameters of φ 1.6 and φ 1.8 meters are supported on piles with diameters of φ 1.8 and φ 2.0 meters. Tie beams are not set for those with good geological conditions between pier columns and piles. Tie beams are set for those with poor geological conditions and high pier shafts, which are consolidated with piles and piers cast in situ. A 5.4-10.2cm thick concrete leveling layer is set on the top of the deck box girder, guardrails are set on the left and right sides of the bridge, and expansion joints are set at corresponding parts of the structure.

expressway Construction organization design (with tunnel project)
The two tunnels are two lane one-way two hole tunnels with separate up and down directions. The two tunnels are designed to have a clear width of 9.75m and a clear height of 5.0m. The maximum excavation width of Class II surrounding rock is 12.44m, and the maximum excavation height is 9.88m. The tunnel adopts anchor shotcrete as initial support and composite lining. This paper includes the construction of tunnels, earthworks, medium and small bridges, pre tensioned, post tensioned slab girders, and box girders. Project construction characteristics: the tunnel is short, the excavation section is large, the burial depth is shallow, the geological conditions are poor, there is groundwater, the valley is narrow, the construction is reverse slope, and the conditions are difficult.
