摘要
从施工工艺、作用机理等方面对目前普遍应用于基坑支护中的喷锚支护和土钉墙进行分析研究,并通过工程实例,比较了喷锚支护和土钉墙在水平位移、安全性能等方面的差异。在场地狭小、变形位移要求较严格等情况下,采用喷锚支护安全可靠;在土质粘性好的情况下,采用土钉墙经济效益好,节省造价。
The paper discussed construction technique and function mechanism of bolting support and soil nailing, which are often used in retaining and protection of foundation. Horizontal displacement and security analysis is compared in bolting support and soil nailing with a project example. When construction field is narrow and deformation displacement request is strict, safety of foundation pit can be guaranteed by bolting support,when on the condition of high-viscosity soil, soil nailing can save construction cost effectively.
