摘要:
土坡的变形是判断其是否安全的重要监控指标,文章提出了虚拟开挖应力的概念模拟土体开挖状态,通过等于2倍静止土压力的虚拟释放应力还原非弹性半无限体的开挖状态至弹性半无限体状态,建立了基于Mindlin解的素土边坡变形计算方法;利用编制的程序讨论了不同因素对素土边坡变形的影响。结果表明:素土边坡土体的最大侧向变形点约在边坡0.75倍开挖深度位置,其最大竖向变形点为靠近侧壁约为0.3H的位置,随着土体内摩擦角的增加边坡变形呈近似线性减小,随着边坡坡角的增大其侧壁最大侧向变形也逐渐增大。
Abstract:
Soil slope displacement is an essential monitoring index about its safety. Virtual excavation stress assumed as two times the static earth pressure is used to simulate the excavation state of soil slope, and restores it to elastic semi-infinite state. Base on the Mindlin solution, a calculation model of soil slope displacement is established under the virtual excavation stress loaded on the face of excavation plane. The calculation program is made to discuss some influencing factors. The result shows that the location of max lateral displacement of soil slope is at about 0.75 excavation depth and that its max vertical displacement on the top is at the distance about 0.3 excavation depth. The soil slope displacement is positively correlated with soil inner friction angle, soil inner cohesion and slope inclination.
