1 Project Overview The project is located in Xin Cai County Wenying Village Committee, reinforced concrete simply supported beam bridge, solid structure, no obvious weathering and erosion phenomenon. The bridge is 70.0m long and 5.0m wide and has a total of 7 holes. Each pier consists of two reinforced concrete foundation piles with circular cross section, and the structure above is composed of “T” beam. 2.5m from the ground pile diameter of 1m, the above diameter of 0.6m, the various sections of the cross-sectional dimensions and other parameters in Table 1. The bridge far from the village, north of Newbridge more than 25m, south from the piers and optical fiber communication cables were 25m and 35m, the surrounding environment in general. The whole work
