The "critical depth" of deep foundation.
深基础的临界深度；
For a tank foundation with a relatively thin soft deposit and undrained shear strength increasing with depth, the edge shear failure is likely to be the critical one.
一罐基础和较薄的柔软的存款和不排水剪切强度随深度增加，边缘的剪切破坏可能是至关重要的。
Based on the theory of chip dynamics and it's breaking foundation in the formation process of side-curl short-spiral chip, the critical depth-of-cut is formulated.
