深基坑工程监测项目的选择及方法研究

深基坑工程在施工过程中会引起围护体系结构内力的变化和位移,基坑内外土体变形和周边建(构)筑物的位移而发生意外,通过施工监测对得到的各种信息进行分析,及时发现问题,为施工提供及时的动态信息,以便制定应变(或应急)的措施,保证基坑及结构施工安全,达到动态设计及信息化施工的目的。该文根据不同基坑类型确定基坑监测的项目选择及监测方法的研究。

Deep foundation pit construction will lead to change in structural internal force and displacement of support system, deformation in soil mass inside and outside the pit, and displacement of buildings and structures in the periphery, sometimes having unprecedented results. By analysis of varying information from construction monitoring, we can find issues in time, provide construction with dynamic information, make emergency measures to ensure safety in pit and structure construction and achieve dynamic design and informatized construction. This paper deals with selection of monitoring items and methods based on different types of foundation pits.
