Research On Design Of Supporting Structure And Construction Organization Of Deep Foundation Pit

The growth of economy promotes the progress of civil science and technology,which makes the construction of high-rise buildings possible.The social progress makes people move from the countryside to the city in large quantities.The limited urban construction area makes the building develop towards the height,and the excavation depth of foundation pit continuously deepens.Different places different natural conditions,economic development,make the distribution of soil water distribution pipelines buried underground situation is different in eastern coastal regions because of geographical reasons and sediment silt formed on the ground,causing silt soil liquefaction soil distributed widely in the northeast southwest plateau area,due to the low temperature causes depth of frozen soil are widely distributed and thicker,it caused great difficulty for deep foundation pit excavation.In this paper,before the design of concrete foundation pit support engineering,the previous theoretical research and experimental research on foundation pit support numerical simulation analysis,a large number of foundation pit support examples are introduced.Then,taking Fuxin Central Hospital with complex soil conditions as an example,the type selection design of foundation pit support in Qi is carried out.Then,the key points involved in foundation pit design are studied in this paper,hoping to provide reference for related foundation pit engineering design.
