Risk Analysis And Support Technology Design Of Deep Foundation Pit Construction In Lingshanwei Parking Lot Project

In this fastdeveloping society building space is particularly important.In order to make full use of the land,a large number of highrise buildings are emerging,and the deep foundation pits projects which are brought along with it are also rapidly developing.Because of the increasing size and depth of excavation of deep foundation pits and the complex geological environment,the construction of deep foundation pits has become more and more complex.Because the development of the deep foundation pit project is not yet mature,accidents caused by management,technology,and other reasons have been common in recent years,and have brought many adverse effects.Therefore,strengthening the management of risks in the process of excavation of deep foundation pits and preventing and controlling potential risks are of great practical significance for ensuring the safety of deep excavation construction.Based on the related theories of risk management,the thesis draws on the research conclusions of the scholars on the construction of deep foundation pits and combines with the actual conditions of the construction of deep foundation pits in China to identify construction safety risk factors for deep excavation.An empirical study on safety risk management was conducted to establish a model for safety risk factors in deep excavation construction.Comprehensive fuzzy calculations were used to valid-ate the model.The results were further explained and discussed.Finally,a deep foun-dation pit excavation suitable for China Shipping is proposed.It is hoped that through the research in this paper,the construction development status of the deep foundation pit excavation construction safety risk management proposal will provide targeted rectification measures for the construction of the deep foundation pit excavation in the world,and the level of its risk management.
