An extended Mohr Coulomb failure criterion is used to allow for shear strength variations as a result of changes in matric suction. Effects of various rainfall events, hydrogeological conditions and use of protective cover on the cut slope are investigated.
计算中采用延伸的摩尔-库伦破坏准则以便考虑基质吸力对抗剪强度的贡献,研究了降雨特征、水文地质条件及坡面防渗处理等因素对暂态渗流场和斜坡安全因数的影响。
The flow of water through unsaturated soil is primary a function of matric suction and gravity.
非饱和土中水流的驱动势为基质吸力和重力。
