该文介绍了预应力管桩在软土层深基坑支护中的应用。在设计过程中,要充分考虑预应力管桩在支护结构中的作用,同时考虑锚索腰梁与管桩间摩擦力不够的问题,增设腰梁挂筋等措施防止锚索腰梁的下滑,以确保支护结构的精确性和安全性,从而满足工程需要。 This paper introduces the application of prestressed pipe piles in deep foundation pit support in soft soil. In the design process, we should give full consideration to the role of prestressed pipe piles in the support structure, taking into account the lack of friction between the anchor beam and the pipe loft, additional measures such as hanging the waist beam to prevent the decline of the anchor lumbar beam , To ensure the accuracy and safety of the support structure to meet engineering needs.
