摘要

In a layered lithosphere slipping system, there are many pores filled of fluid with a certain pressure. Supposing the floating force caused by the pore fluid pressure in the slipping plane is Ff, the loading weight of bedding slipping block is ST, then a new index of R, the ratio of Ff to ST, can be given, that is very important to describe the layered slipping motion of lithosphere being easy or difficult. Actually, shearing strain in lithosphere can outstandingly change the value of R.
