中寨大桥钢栈桥设计及计算(国外英文资料) The bridge design and calculation of the bridge A: introduction to engineering The XXXX highway section x is the starting point of the x contract, which has a total length of 19.15 Km. For the convenience of construction, as far as possible to reduce engineering disturbance to the residents, guarantee the smooth construction machinery and material approach and the protection of the original natural infrastructure, before construction to be well versed in the main line construction road, in the village bridge (K118 + 440) of 0 # to 4 # pier between across the village reservoir spillway need could take a while. The water of the spillway of zhongzhai reservoir is 10 meters in width, and the soil is red clay, dust and soil. The K118 + 440 is a 27m bridge in the spillway bridge, with a gravity type U bridge, and the base and body of the bridge are made of C20 concrete. The upper structure was fitted with the berley frame. The bridge is a double-breed-single-layer standard beret frame for the upper bearing structure. Bridge location and layout According to the location and route of the construction road, make sure to make the connection with the construction. According to the location, topography, high difference and geology of the two sides, the Central Line of the bridge is determined. Measure the width of the canal and measure the cross-diameter of the bridge. The length of the bridge is 27m, the diameter of the bridge is 26.5 m, and the bridge has a width of 4.0 m. The 321 military beret beam, 25a type of steel beam, and the steel bar of the steel bar, and the steel bar, the steel bar, the steel bar, the steel bar, the steel bar, the steel bar, the steel bar, the steel bar, the steel bar, the steel bar, the steel bar, the ? The upper part is a double row single-layer beret girder truss; The allocation of beams is 50cm by 25a. Layout of the benet bridge construction; The top surface is covered with a steel plate with a steel bar. Technical specifi
