A Research On Optimal Design Of Foundation Pit Support And Dewatering In Huludao

With the development of the economy in China,people's demand for construction space is increasing.While the building size of the construction gradually becomes higher and deeper,the enlargement of building size requires higher standard in foundation pit engineering.So the importance of foundation pit engineering is increasingly becomes prominent.Foundation pit engineering is a comprehensive engineering which combines so many influencing factors such as geotechnical engineering mechanical engineering and so on.The design and construction of support and dewatering should not only be reasonable,but also reduce the engineering cost to the maximum extent on the premise of ensuring safety.At present,the design of foundation pit supporting and dewatering is more and more mature,and the economy is becoming more prominent in the design factors.There are many characteristics of foundation pit engineering in China,such as region,diversity,comprehensiveness and so on.How to optimize the design according to local conditions and time,and how to minimize the cost of the project is the top priority of the whole foundation pit engineering.This thesis firstly introduces current situation?research contents and research methods of foundation pit engineering at home and abroad,and expounds the general situation of the proposed project and site conditions.Next,according to the analysis of common support types and with the method of the application experience and the comparing exclusion the support scheme of foundation pit is preliminarily selected.Then according to the actual site conditions,the final optimization design is carried out for the dewatering engineering of support engineering.Finally,the "Lizheng Deep Foundation Pit Supporting Design Software" is used to simulate and analyze the design scheme of foundation pit engineering,and the rationality of the scheme design is verified by comparing with the field monitoring scheme.The software simulation results are compared with the field monitoring data,and the rationality of the scheme design is verified reversely,which provides some design optimization experience for the similar foundation pit projects in the future.
