摘要
介绍了规范中复合土钉支护基坑边坡的稳定分析方法以及有限元分析方法。针对具体的水泥搅拌桩土钉支护工程实例,分别采用这两种方法分析基坑的稳定性,二者计算结果一致。同时计算表明由于基坑土体强度较低,滑动面的形式表现为"通过土钉末端,切割搅拌桩的深层滑动"。此结果可为设计和施工提供一定的参考依据。
Two methods of stability analysis of soil nailing support of deep foundation pit including criterion method and FEM are introduced. As for engineering example, stability of deep foundation pit is analyzed through the two methods. The result indicates that the cement mixing pile slide via the end of the soil nail is due to the low intensity of the soil in the foundation pit. some useful conclusion are obtained, which is provided as conferences for design and construction.
