Deformation Monitoring Technology And Engineering Practice Of Deep Foundation Pit Engineering

This paper studies the technical specification of deep foundation pit,demonstrates the development trend of foundation pit in recent years,analyzes the contrast of the existing technical specifications,and summarizes the common and differences of technical specifications in Shanghai and other places.At last,through the foundation pit deformation monitoring project of the Jindu building,and the main points of knowledge of deformation monitoring of deep foundation pit are summarized.in order to achieve a timely manner to the design,construction,construction and supervision units feedback monitoring results,the implementation of information construction purposes.The specific contents include:1.the status quo and development of deformation monitoring technology of Deep Foundation Pit,commonly used equipment and monitoring project;2.Analysis of various methods the observation of deformation of deep foundation pit,and reduce the method to analyze the error in the monitoring;3.carry out research on monitoring technology specification and method and engineering practice of deep foundation pit change,comparison of Chinese and foreign technology differences,analysis of China’s local representative;4.alloy building deformation monitoring of deep foundation pit excavation monitoring project practice,detailed procedures and matters needing attentionThrough the study of this paper,the following conclusions are drawn: 1.foundation pit monitoring is an important guarantee for the construction of the modern construction project.Monitoring is a long way to go,from the early to mid reconnaissance observation,finally the monitoring results of the data analysis and comparison of early warning,every step is related to the security problems in the process of construction.2 deformation monitoring in the process of error is inevitable,monitoring work,should always use the same instrument,fixed station and post view,a fixed level of the line should be fixed personnel observation.
