中文摘要：

基坑围护作为一项临时工程，作用期限短。土钉墙是一种应用较为广泛的基坑围护形式，将土钉墙中的钢材用竹材代替，作为基坑工程中的主要受力构件，既能满足强度上的设计要求，又能满足时间上的设计要求，并且基坑作用期满后，竹材自动腐烂，不会对后续工程造成影响，也会减轻环境上的污染并降低造价。

英文摘要：

As a temporary engineering, foundation excavation protecting is of short construction period. Soil nailing wall is a widely applied kind of foundation excavation protecting. Instead of steel in the soil nailing wall, bamboo is used as the main force component. The design requirements of intensity and construction period are both satisfied, and moreover, split bamboo soil nailing will reduce the costs and get decomposed when the foundation excavation engineering is finished, which makes little influence on later engineering and reduces environmental pollution.
