Application of Geotechnical Survey in the Multi-storey Basement Building Construction
In our country,the talent attraction policy of metropolis is gradually optimized.The population is grow-ing rapidly.The population density of large shopping malls,hospitals and high-rise residential areas is increasing,and the requirements for basement space are getting higher and higher.Therefore,geotechnical investigation plays a pivotal role in the construction process of multi-storey basement buildings.Taking a multi-storey basement con-struction project in Central China as an example,in line with the principle of"safety first,economy as a supple-ment",this paper analyzes the stability of multi-storey basement excavation foundation pit by means of surveying and mapping,geological drilling,in-situ test and laboratory test.It is suggested that pile row support should be a-dopted in the excavation of foundation pit.At the same time,By considering comprehensive safety and stability,e-conomic applicability and construction difficulty and other factors,the foundation treatment scheme is analyzed,and the suggestion of using manual digging pile is given,which plays an important role in the safety and stability of building construction.
