%X 论文以实际工程为背景，通过室内模型试验研究了既有重力式挡墙在新增荷载作用下的承载特性。研究结果表明，墙背土压力随着施加荷载的增大而增大，且墙底最大、墙中最小；墙体位移较小并伴有绕墙趾转动的趋势；墙背土压力介于静止土压力与主动土压力之间的弹性状态，保持稳定。<br />
The thesis is based on practical engineering. The bearing characteristics of existing gravity retaining wall under new load are studied by indoor model test. The results show that the earth pressure behind the wall increases with the increase of the applied load, and the earth pressure at the bottom of the wall is the largest and the middle is the smallest. The wall displacement is small and has a tendency to rotate around the toe of the wall. The elastic state of the earth pressure, keeping stable, behind the wall is between the static earth pressure and the active earth pressure.
