摘要:

通过对开挖荷载的模拟,使得开挖后土体的受力和变形满足弹性半无限体的要求。基于弹性半无限体的MINDLIN应变解,首次推导出基坑边坡变形的理论解,并利用该解研究了不同施工步数条件下基坑边坡侧向变形和竖向变形的规律,并据此提出了边坡加固方法和施工措施。研究结果表明:不同的施工开挖步数条件不但影响边坡的最大侧向变形及其分布,而且还影响边坡的破坏形式; 与有关实测数据比较,该方法在计算边坡变形方面合理、实用。

Abstract:

Through analysis of simulation for excavation load, the force and deformation would meet the demands of elasticity semi-infinite solid. And the theory solution of soil slope deformation was deduced on the basis of MINDLIN strain solution. Authors made a study of the regularity by considering construction steps. Meanwhile some measures are put forward for the reinforcement and construction of slope. The results show that the different construction steps affect not only the value of the maximum deformation of slope and its distribution but also its failure model. The rationality of the results is proved after comparing with the field measurements and FEM calculation.
