摘要
依据混凝土结构设计规范，考虑面板在冲剪和直剪下的承载力，以及近似考虑面板的抗剪力，设计了6种承载模式，在工程实例的基础上对此进行分析。研究表明，综合考虑各个抗滑力，对于合理确定土钉支护安全系数具有重要意义，可为规范的编制提供参考。
Judging by design specifications of concrete structure, it considers the panel weight between punching and cutting and panel shearing force, and six modes of weight are designed, which carries on analysis on the base of engineering practice. The research shows that conforming reasonably assurance coefficient of soil nail support has a important significance in view of various skid resistence.
