通过对上扬子区内川东华蓥山地区沉积盖层的系统采样，全面测试分析岩石力学参数和物性参数，按层滑基本理论，将其中∈1q、S1l-O3w、T1j-J2l和J2s-J 3p这五个具有岩性强度低、物性参数小的泥页岩、膏盐岩或煤层段，划分为滑动层位，其余层段为非滑动层位。把整个扬子区块内的上、中、下三部分，用抗压强度、抗张强度、抗剪强度、强性模量和泊松比等岩石力学参数及纵波速度、横波速度和岩石密度等物性参数进行比较，发现整个扬子区块的滑动层位具有一致性。且滑动层位可以作为区域性油气盖层。

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.
