摘要
为解决强流塑特性地质条件下桩基与基坑施工时存在的桩位偏斜、群桩偏移、基坑变形过大等难题,以福建莆田涵江医院项目为工程背景,提出了以桩型选型优化与新型连接技术为核心的桩基施工实施路径,以及以围护体系与工序优化为核心的围护施工实施路径,从而达到节约建设成本、缩短施工工期、保证工程质量与安全的目的,可为类似项目提供借鉴。
To solve the problems of pile position deviation,pile group deviation and excessive deformation of foundation pit under the geological condition of strong flow plastic characteristics,based on the project of Hanjiang hospital in Putian,Fujian Province,the implementation path of pile foundation construction with optimization of pile type selection and new connection technology as the core and the retaining support construction with support system and process optimization as the core are put forward,so as to save the construction cost,shorten the construction period and ensure the quality and safety of the project.It can provide reference for similar projects.
