摘要
在挖方工程中,开挖面形状、开挖面角度直接影响到滑动面的形状和滑动面的计算参数。由于开挖的影响,滑动面可能发生在老填土或者新填土中,滑动面上的应力状态不是库伦主动状态,因而不能采用传统的库伦土压力理论计算主动土压力。探讨了不同情况下土压力计算参数的取值和计算方法,提出了建议。
In the digging project, the shape and angle of the digging surface will influence the slip surface＇s shape and parameters. As a result of digging, the slip surface will take place in the old or new fillings and the stress state will not be the Coulomb initiative state but another one, so we can＇t calculate the initiative soil pressure using the traditional Coulomb theory. In our study, we discuss different evaluation and counting ways to calculate the soil pressure parameters and put forward some suggestions.
