Research of shear strength theories of unsaturated soil

  title={Research of shear strength theories of unsaturated soil},
  author={Wang Qi Zhi},
Based on the state of existence of pore water in soil, some doubtful points about Bishop's formula are discussed. A problem is clarified: the reason why the stresses that determine the strength and deformation of unsaturated soil are different is that an inner stress, different from effective stress, exists in unsaturated soil, which can not be transferred, but only affects plastic deformation. In addition, the parameter test methods of shear strength theories proposed by Fredlund, Bishop, and… CONTINUE READING
