Mass loss is linear with sliding friction works and in proportion to sliding distances.
磨损量与滑动摩擦功呈线性关系，与滑动距离成正比。
The result shows that in the ring-block sliding wear test, with time prolonging, the friction coefficient of all samples becomes more and more stable, and the mass wear loss increases.
结果表明：在环-块滑动摩擦实验中，随时间延长，试样摩擦系数均趋向平稳，质量磨损量均增长。
The relieving platform limits the sliding plane, and the sliding mass at this time is no longer a voussoir, so, Rankine theory and Coulomb theory cant be applied to calculate the earth pressure.
减压平台限制了墙后滑动面，此时滑动土体不再是一个楔体，无法采用朗肯理论、库仑理论计算土压力。
