    Abstract
  • Assembled prestressed fish-belly beam steel support is a new type of support structure system for deep foundation pit , which is green and recyclable. It can form a large excavation space and effectively control the deformation of foundation pit. Taking a foundation pit project in Shanghai as an example, the application and implementation effect of assembled prestressed fish-belly beam steel support in deep and large foundation pit engineering are introduced. The monitoring results show that the prefabricated prestressed fish belly beam steel support has a good effect in deep and large foundation pit engineering in soft soil area, and has remarkable effect in engineering safety control and economic benefits, which can be used as a reference for similar foundation pit engineering.
