Abstract
By systematically collecting samples from depositional covers in Huayi ng Mountain, Eastern Sichuan, Upper Yangtze plate, and comprehensively testing a nd analyzing their rock mechanics parameters and rock physical parameters, the l ower Cambrian, upper Ordovician, lower Silurian, upper Permian and middle-lower Triassic formations in the studied area are grouped into typical major sliding l ayers according to that they are composed of mud stone, shale, gypsum and coal- beds, and characterized by lower resistivity competent, lower physical parameter s etc., and the rest are non-sliding layers. Comparing the up, middle and lower parts of the formations on the area by rock mechanics parameters: Rp, Rt, Rs E, λ etc. and the rock physics parameters: Vp, Vs, D etc., it has been found that the major sliding layer are basic similar in whole Yangtze plate, and the slipi ng layers could play an important role of being a regional covering strata.关键词
