基于PIV技术的反倾层状结构边坡模型试验研究
Experimental Study of Anti-dip Layered Slope Model Based on PIV Technology
摘要
Abstract
The process of deformation and failure of anti-dip layered slope under pressure load at slop top are measured based on Particle Image Velocity (PIV) to analyze deformation and failure mechanism.The results show that,(a) when the pressure load is relatively small,there is little deformation,the displacements appear at the upper part and the back of model slope,and the strain concentration is formed in parallel with rock formation;(b) with the increasing of load,the deformation is also increasing,the displacement sense of upper part of slope becomes opposite,and a horizontal run-through strain concentration appears which gradually moves down until it runs through the slope from slope toe to slope back with a angle of 15-17 degree to horizontal line;and (c) when the slope is at complete failure stage,there are three parallel fracture zones in model slope,the one at the bottom of slope appears firstly and the one at the uppermost part of slope appears at the latest,and the failure degree gets increasing from top to bottom of slope.关键词
