Chapter 2 establishes a helicoid model of the 3D curved shock surface, which is a fundamental means for investigating the sweep of the 3D shock surface In chapter 3, the first step is to make definitions and detail concepts about various viewpoints of shock surface sweep. Secondly, those sweep angles of the 3D shock are calculated. After that, with the aid of the helicoid model, two general structure similarity variables are derived which are independent of any model, and their importance in shock structure investigations is discussed.

So the systematically study of loess landslides are emergently needed. Based on detailed investigation and survey of characteristics of environmental geology, engineering geology, hydrometeorology in Tongchuan, the distribution characteristic and the outer, inner factor of loess landslides are studied; and it is concluded that the rainfall and artificial engineering activity are the leading causes of loess landslide among various factors. Through plenty of tests of soil samples, it is researched that the loess"s physical mechanics characteristics, the loess landslide"s formation mechanism and kinematics mechanism.
