Toppled rock body classification method

Abstract

The invention provides a toppled rock body classification method. The method comprises the steps of setting seven classification indexes for evaluating toppled rock bodies, wherein the classification indexes include a deformation feature, a rock stratum tilt angle, an inter-stratum maximum extensional amount, an inter-stratum unit extensional amount, an unloading deformation feature, a weathering degree and a longitudinal wave velocity; and according to comprehensive judgment of the classification indexes, classifying the toppled rock bodies into three types: an A-type extremely strong toppled cracking region, a B-type strong toppled cracking region and a C-type weak toppled transitional deformation region. According to the method, the classification indexes can pointedly describe basic deformation cracking features of the toppled rock bodies; the field workload is small; and in the aspect of evaluating the stability of the toppled deformed rock bodies, the effect of getting twofold results with half the effort can be achieved due to high pertinence.

Description

technical field [0001] The present invention relates to rock mass classification. Background technique [0002] After the brittle rock layer is toppled and deformed, the rock mass is broken. According to the general classification scheme of rock mass structure, it is difficult to describe the degree of toppling deformation. In the prior art, the rock mass structure classification scheme or the rock mass quality classification method is usually used to evaluate the rock mass toppling deformation, wherein, the classification indicators of the rock mass structure classification method are: 1. Geological background (lithology, tectonic movement, rock layer thickness) 2 .Structural surface characteristics (structural surface length, structural surface group number, structural surface filling, structural surface cementation degree) 3. Structure shape (giant block, thick plate, block, column, plate, rock block) , the classification results are: 1. Overall massive structure 2. Laye...
