邻近建筑物的高陡人工边坡变形及防护分析

摘要

In order to study the deformation mechanism and safety of a high and steep slope nearby building,located in Chengde city Hebei Province,some numerical researches were carried out,based on the FLAC 3D software package.The deformation and failure mechanism of the slope with designed slope angle was discussed,and the critical slope angle to make the slope safe was proposed.Then,the deformation and safety of the slope was simulated with FLAC 3D when the lattice beam,anchor bolt and anchor bolt were applied on it.Finally,the field monitoring data was also analyzed.Some suggests were proposed and the research can be used in the similar engineering.%针对某近邻建筑物的高陡人工边坡的变形机理及防护问题,利用FLAC3D软件进行了数值模拟研究.探讨了设计坡角情况下该高陡人工边坡变形失稳机理;并建议了该人工边坡稳定临界坡角.在此基础上,数值分析了施加格构梁+锚索+锚杆防护措施后边坡的变形及稳定性.最后,对本边坡工程施工的现场监测数据进行了分析.研究对类似工程设计施工具有指导意义.
