MONITORING ITEM SELECTION AND METHOD STUDY OF FOUNDATION PIT ENGINEERING
XIANG Li-bin;Institute of Geophysical and Geochemical Survey Technology of Anhui Province;
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.
