The Deformation Monitoring And The Research Of The Deformation Mechanism And Law For Deep Foundation Pit

This paper studies the monitoring methods and the construction organization of buildingdeep foundation pit, and it analyzes the deformation law of deep foundation pit in the stage ofexcavation and underground construction based on specific case study. The research of thispaper can provide some references and guidance for the deformation monitoring of buildingdeep foundation pit.The major research works are presented as following:1. It discusses the principles and foundations in the monitoring scheme-making ofbuilding foundation pit, the monitoring methods, the settings of monitoring alarm and theconstruction organization so on systematically.2. It compares on accuracy and operation method between the usual measuring methodswhich are used in the monitoring of building foundation pit.3. It analyzes the mechanism, factors and coping methods of pit deformation in the lightof soil mechanics.4. It studies the deformation law of foundation pit in the stage of excavation andunderground construction based on specific case study and monitoring data analysis.
