摘要
推出大气张力库仑土压力的近似计算方法:假设临界破裂角为已知,可以考虑多层粘性土、坡面任意荷载、水和气压力。提出粘性土的结合水膜可靠连接面积率修正系数等于粘粒含量。推出大气张力库仑抗剪强度公式的Cm形式,Cm是膜的抗剪强度贡献。
It is launched the approximate calculation method of the atmospheric tension Coulomb＇s earth pressure：Assuming that the critical rupture angle is known,can consider multi-layer cohesive soil,slope arbitrary load,water and air pressure.This paper put forward combined water membrane reliable connection area ratio correction coefficient of cohesive soil is equal to the clay content and launch the atmospheric tension Coulomb＇s shear strength formula form of Cm .The Cm is the shear strength contribution of membrane.
