【摘要】 以某车站内扶壁式挡土墙为研究对象,在填方路段进行墙背土压力的试验研究。此试验是在挡土墙的扶肋和肋间填土上按照一定的间距安装静土压力盒,进行土压力数据的测试,结果表明:假想墙背的土压力分布表现为明显的非线性,最大值发生在墙体中间位置,合力作用点比库伦理论提出的位置更高。更多还原

【Abstract】 As the study object of the counterfort retaining wall in a station, the wall-back earth pressure is experimented and studied in the filling section of road. The experiment carries out the test of the earth pressure data by installing the static earth pressure box on the ribs and the filling between ribs of counterfort retaining wall according to a certain space. The results show that the wall-back earth pressure distribution is obviously nonlinear, the maximum value is in the middle of the wall, and the position of pressure force is higher than the theory of Coulomb.更多还原
