| Abstract: | The new underground underground comprehensive pipeline corridor underneath the existing underground pipeline corridor has the characteristics of narrow construction space,high construction deformation control requirements and large construction risk.This article takes the underpass construction of the comprehensive pipeline corridor of Baoshan Scenic Area Avenue as an example.The foundation pit excavation and supporting scheme and main points under the existing tunnel are analyzed and demonstrated,which can provide a reference for similar projects in the future. |
