锚杆框架梁支护膨胀土路堑高边坡稳定性分析
Analysis of slope stability of expansive soil multistage roadcut slope under the action of anchor frame beam
摘要
Abstract
Taking the three-level expansive soil roadcut slope of Wanzai-Yichun Freeway in Jiangxi Province as the research object,we use the finite difference method to carry the three-dimensional numerical calculation of slope stability under the action of anchor frame beam supporting structure and the slope.The anchor parameters of the different level slope influence on the safety factor and deformation of high roadcut slope are analyzed.The results show that the slope safety factor does not increase with the increase of anchor length,and it has a peak;that the influence of anchor setting angle of the slope on the safety factor is small,but it has significant effect on the slope deformation.The optimal anchor angle is different,as the rate of the three levels slope is different.关键词
