地震作用下非贯通节理岩体斜坡破坏的物理模型试验研究
Physical Model Test of Rocky Slope Failure Containing Intermittent Joints under Earthquake Action
摘要
Abstract
In general the failure development process of high slope under seismic action is very short and intense, the failure mechanism is relatively complex. In this paper, a model test is a-dopted to study the response of intermittent joints rock slope under seismic load. The results in-dicate that the maximum strain is on the joints, the strain on upper part of the model is larger than the lower part. The coalescence mechanisms is complex, mostly are tensile-shear mixed fail-ure. The coalescence of joints didn't imply the destruction of the slope, but destroy the integrity of the slope, and made it in the critical condition. The physical test reveals the response and fail-ure mechanism of this type slope under the earthquake action, it will provide a useful reference and guide for theory application and engineering practice.关键词
