老旧桩基再利用研究

Study on reuse of old pile foundation

在越来越多的拆迁建设项目中,不可避免地要面对旧桩基的再利用问题,而有效地解决旧桩基的再利用问题,可以节省工程成本,并有效地节省施工时间。文章以上海某工程为例,基于地基土工程性能表现和现有老桩情况,提出新旧设施的处理方案,并从造价、工期等多个角度对方案进行比较,选择合适的方案,为后续类似工程提供参考。

In more and more demolition and construction projects,it is inevitable to face the reuse problem of old pile foundation,and effectively solve the reuse problem of old pile foundation,can save the project cost,and effectively save the construction time.Taking a project in Shanghai as an example,based on the performance of the foundation soil engineering and the situation of the existing old piles,this paper puts forward the treatment scheme of the old and new facilities,compares the schemes from the perspectives of cost,construction period and so on,and chooses the appropriate scheme to provide reference for the subsequent similar projects.
