2. Design standard According to the requirements of the assignment, the design load of this bridge is steam level 20 and hanging level 100. The bridge is 7.5m wide and the carriageway is 6.5m wide. Cement concrete deck is adopted. 3. Geology of the bridge site The landform of the bridge site belongs to the intermountain valley landform, and the terrain elevation varies from 37.00m to 45.00m. The two banks are the alluvial terraces of the Xinxing West River. Because of water storage and power generation, the water depth is always about 3.00m~4.00m. Stratum characteristics at the bridge site are Quaternary alluvium (clay, loam and round gravel) and Cambrian sedimentary rock (weakly weathered sandy shale, strongly weathered sandstone and weakly weathered sandstone) from top to bottom. The seismic fortification intensity of the site is 6 degrees, and the design basic seismic acceleration value is 0.05g. 　　 　　

This drawing is the structural drawing of simply supported beam abutment cap reinforcement

Detailed drawing of general structural node of prestressed bridge abutment

Part of the bridge plane is located on the right turning curve of JD34 (K537+536.9), R=1900m, and part is on a straight line; The vertical slope of the elevation is i=-4.8% (slope length 840), and the stake number of adjacent grade change points is K537+980. In order to improve the driving conditions, the left side adopts a continuous structure of two links (four holes one link+four holes one link), and the right side adopts a continuous structure of two links (four holes one link+four holes one link); There are 6 expansion joints in the whole bridge.

The cross slope of cap beam is positive when the design line of the route goes downhill to both sides. The pile foundation of this bridge adopts end bearing piles. The pile foundation shall ensure that the edge of the rock surface enters the 3D of the complete moderately weathered rock layer, and ensure that the pile length is not less than the design pile length. D is the diameter of the pile foundation. This drawing is applicable to 40m span. All dimensions in this drawing are in cm except elevation in m. The bearing capacity of the abutment base is not less than 400kpa. The thickness value Hn in the cushion stone thickness table corresponds to the cushion stone elevation mark Zn. ...... 5 sheets in total
