Mechanism Analysis of Yingzuiyan Collapse in Shuibuya Reservoir, Western Hubei Province
摘要
Abstract
Yingzuiyan collapse is a typical reverse strata collapse, belongs to ripping-type collapse, and formation of which is under the control of terrain geomorphology, lithology, geological structure, rainfall and other factors. Upper-part and under-part of the collapse are composing of rigid rocks, while the middle-part has got a weak layer, which makes a sandwich-type lithology combination. This type of rock structure is the key factor influence the stability of Yingzuiyan collapse, while the infiltration of rainfall to the rock mass fissures accelerated the collapse occurred. Geological environment conditions and genetic mechanism analysis of Yinzuiyan collapse indicated that the collapse body is in an unstable state, with the evolving cracks in the existing dangerous rocks mass, the next landslip may happen in the near future.关键词
