摘要

基坑支护结构作为一种临时支挡设施，如何做到确保安全的前提下降低工程造价、提高施工速度是工程界普遍关心的问题。为此，结合实际工程需要，提出一种施工安全快速、造价低、可回收利用、绿色环保的新型基坑支护型式——十字形装配式基坑支护结构。介绍并设计了该支护结构格构单元的结构选型和计算方法。依托南宁市五象新区某项目做了基坑支护现场试验，结果表明试验值与计算值相近，证明了设计方法的正确性。在该基坑支护结构支护下，基坑稳定性、基坑变形、支护结构强度均满足规范要求，可以在类似的工程中推广应用。

Abstract

Foundation pit supporting structure is a temporary retaining facility

how to reduce the engineering cost and improve the construction speed under the precondition of ensuring the safety is a common concern. To satisfy the engineering demand

a new type of foundation pit supporting structure

cross-shaped assembled foundation pit supporting structure

is proposed

which is safe

rapid

low cost

recyclable and environmentally friendly. In this paper

the structure selection and calculation method of the lattice element are introduced. The field test relying on a project in new Wuxiang district

Nanning

Guangxi province

shows that the experimental values are similar to the calculated values. It proves the correctness of the proposed design method. With the support of the foundation pit supporting structure

the stability of foundation pit

deformation of foundation pit and the strength of support structure all can meet the requirements of specification

so it can be applied in similar projects in the future.
