Study on Geological Survey and Shear Wave Velocity Characteristics of a Building Site in Changchun City
Taking a proposed project in Changchun City,Jilin Province as the research object,based on the relevant technical specifications,the engineering geological investigation is carried out by means of drilling sampling,shear wave velocity test and other methods.The lithological distribution and hydrogeological conditions of the strata within the site are identified.The characteristic value of foundation bearing capacity is determined.The permeability coefficient of the soil layer,the type of site soil and the degree of liquefaction,etc.are judged.By using the four common function models,a fitting function with higher accuracy for different soils is selected,providing reference for the verification and prediction of shear wave velocity for the construction of the area around the site.Based on the engineering geological conditions of the site,in combination with the characteristics of the proposed building,the foundation design and construction program recommendations are proposed.
