摘要
采用锚杆(索)墙对基坑边坡进行支护,可以有效地抑制基坑裂隙的扩展和发展,阻止基坑的侧向变形。利用FLAC3D的基本原理,对贵阳市某基坑的锚固设计进行模拟和分析,用模拟所得的计算结果与实际施工后基坑的进行比较,结果表明:使用FLAC3D软件对深基坑边坡进行稳定性分析是可行的,因此可以应用数值模拟方法提前对基坑施工过程进行仿真模拟,预测变形的发展变化,发现工程中薄弱部位,以指导设计及施工中采取进一步有效措施。
By using anchor （cable） wall in the slope supporting, it could effectively inhibit the expansion and development of cracks and prevent lateral deformation of the foundation. This paper is about the analysis and simulation of anchor design with the basic principles of FLAG3D carried out on a foundation in Guiyang. Com- pared to the actual construction, the simulation results show that the use of FLAC3Dsoftware in analyzing the sta- bility of deep foundation is feasible. Therefore numerical simulation method can be applied to the foundation con- struction simulation to predict the development of deformation change, identification the weak area and guide the construction to take further effective measures.
