Abstract. Land subsidence caused by dewatering of deep foundations pit has currently become the focus of prevention and control of land subsidence in Shanghai. Because of the reliance on deep foundation dewatering pit projects, two comprehensive test sites were established to help prevent land subsidence. Through geological environmental monitoring during dewatering of a deep foundation pit, the analysis of the relation between artesian water level and soil subsidence, some basic features of land subsidence caused by dewatering of deep foundation pits are elucidated. The results provide a scientific basis for prevention and control of land subsidence caused by dewatering in deep foundation pits.

Abstract. At present, large-scale engineering construction activities, especially deep foundation pit dewatering, are important factors of land subsidence in Shanghai, which induces uneven land subsidence. To solve this problem, this paper puts forward a technical approach to prevention and control the land subsidence. Based on the practice of joint work by multiple administrative departments in Shanghai, this paper further combines the technology and management measures effectively, and summarizes the management system of land subsidence control for deep foundation pit dewatering. Meanwhile, this paper provides the key workflow, starting from the whole process control of construction project for feasibility demonstration, design, construction and completion. The practice shows that the whole process of deep foundation pit dewatering control and management provides a powerful guarantee for land subsidence prevention and control.

The Empirical Analysis

Risk management consists of Risk Identification, Risk Measurement, Risk Assessment, and Risk Monitoring and Control. This paper based on An office building in Dongying, uses Monitoring data to analyze, in order to gain an applicable Risk Management Practice. This article suggest we have to do the survey work well and also should pay attention to the empirical analysis of experts and field technicians at the same time to analyze risk to deep foundation pit engineering.

Abstract. In order to analyze land subsidence caused by the dewatering of a deep foundation pit in Shanghai, numerical analysis, field testing, automatic monitoring and other technologies are applied to research land subsidence control technologies, covering the whole process during the design, construction and operation of foundation pit dewatering systems. The key technologies are applied to a typical metro station foundation pit in Shanghai, such as the integrated design of foundation pit dewatering and a waterproof curtain, information control, groundwater artificial recharge, etc. The measured data of groundwater level, pore water pressure and land subsidence show a good effect on land subsidence prevention and control.
