Abstract

Abstract

Based on the design method of soil nailing in the current codes for excavation support,the need of global stability checking and local stability checking for soil nailing in design was discussed.It was shown that only global stability checking was necessary when the failure of the soil nailing obeyed the law of elastic-perfectly plastic or hardening.However,local stability checking could make the design more reasonable.Global stability checking were local stability checking were both needed when the failure of the soil nailing possessed of a softening nature.But local stability checking was sufficient when the cohesion of the soil was relatively large.
- soil nailing,
- global stability,
- local stability
