压力分散型可回收锚索在深基坑支护中的应用研究

Research on the Application of Pressure-dispersible Recoverable Anchor Cable in Deep Foundation Pit Support

锚索在深基坑支护工程中被广泛使用,然而施工后锚索仍留在地层中对地下周边环境造成污染,给未来城市地下空间开发带来困难。然而,锚索的可回收性能有效减轻对地下周边环境的污染,降低未来城市地下空间开发的难度,符合可持续发展理念,适应社会发展。文章从锚索锚固原理、回收原理出发探讨压力分散型可回收锚索的可行性和适用性,并结合工程实例分析压力分散型可回收锚索在深基坑支护中的可靠性。

The anchor cable is widely used in deep foundation pit support engineering,but the anchor cable still remains in the ground after construction,causing pollution to the underground surrounding environment,and bringing difficulties to the future urban underground space development.However,the recyclable performance of the anchor cable effectively reduces the pollution of the underground sur‐rounding environment,and reduces the difficulty of future urban underground space development.It con‐forms to the concept of sustainable development,and adapts to social development.This paper discusses the feasibility and applicability of pressure dispersible recoverable anchor cable from the anchoring principle and recovery principle,and analyzes the reliability of pressure dispersible recoverable an‐chor cable in deep foundation pit support with engineering examples.
