摘 要: 采用简化Bishop法,结合2个工程实例对土钉墙进行稳定性分析,采用Matlab软件编程完成复杂的计算,分析了土钉倾角与边坡稳定性安全系数之间的关系,得出土钉倾角与安全系数之间的关系曲线,阐述了两者之间的一般规律:对于不同工程而言,土钉存在一个特定最优倾角,达到这一倾角,土钉的作用能最大地发挥出来,进而减少工程造价。同时,给工程设计人员以启示,避免存在某一倾角对任何工程都是最优的这一误区。
关 键 词: 土木建筑结构;土钉支护;倾角;边坡;稳定性;安全系数

Abstract: This paper analyzes the stability of soil nailing wall based on the simplified Bishop method and two engineering examples.The complicated calculation is completed by Matlab which has powerful calculation and drawing function. The paper analyzes the relationship between soil nailing inclination and slope stability safety factor, obtains the curve of soil nailing inclination and safety factor, and describes general law between the both: soil nailing has different optimal inclination for differrent projects, the role of soil nailing can play globally when it is in the optimal inclination, this can reduce engineering cost. It can remind engineering designers that not all engineerings have the same optimal soil nailing inclination.
Key words: civil architecture; soil nailing retaining; inclination; slope; stability; safety factor
