Research on the Application of Cantilever Pipe-Combination Pile in Deep Soft Soil Foundation Pits
摘要
Abstract
This study focuses on a deep soft soil foundation pit support project in Nansha District,Guangzhou City.A comparative analysis was conducted on the applicability of cantilever pipe-combination pile in deep soft soil foundation pits.In view of the fact that the current computing software does not have a module specifically for pipe-combination pile,a practical equivalent calculation idea is proposed,and the influence of different design parameters,such as pile diameter and spacing,on the deformation and mechanical behavior of the foundation pit was investigated to determine the optimal design scheme.Field implementation and monitoring results demonstrate that the cantilever pipe-combination pile solution meets the safety and deformation control requirements of the foundation pits while significantly reducing construction duration and project costs.This project represents the first successful application of cantilever pipe-combination pile in building foundation pits in the region,providing valuable references for similar engineering projects.关键词
