放坡竹筋土钉墙在软土地区的应用

放坡竹筋土钉墙作为一种新型支护结构形式,已成功地运用于开挖深度为5 m~6 m的软土地区基坑工程。文章分析了毛竹材料作为土钉在软土地区的适用性及放坡竹筋土钉墙的作用机理,总结了竹筋土钉墙的设计要点,结合实际工程案例,验证了该支护结构形式的适用性及合理性,推动了新型环保材料、新型支护技术在岩土工程中的应用,可供今后类似工程借鉴。

Application of Sloping Bamboo Reinforced Soil Nailing Wall in Soft Soil Area

As a new supporting structure, sloping bamboo reinforced soil nailing wall has been successfully used in the excavation of foundation pit which excavation depth is 5-6m in soft soil area. This paper analyses the applicability of the bamboo materials as soil nailing in soft soil area and the mechanism of sloping bamboo reinforced soil nailing wall. And what＇s more, this paper also summarizes the design points. Combined with the practical engineering case, the applicability and rationality of the supporting structures are verified. The application of this new supporting structure can promote the application of new materials and new support technology in geotechnical engineering. This paper provides a reference for similar projects.
