广州南沙软土室内直剪试验与现场十字板剪切试验强度对比研究
Comparative Study on Strength between Indoor Direct Shear Tests and Field Vane Shear Tests of Soft Soil in Nansha,Guangzhou
摘要
Abstract
With the rapid development of the economic construction in Nansha,road surface issues caused by adverse geological conditions have emerged one after another,severely constraining economic growth.Based on a survey project in Nansha,Guangzhou,this study conducts a comparative analysis of shear strength in silt and silty soil through field vane shear tests and laboratory direct shear tests.The results indicate that the vane shear test yields higher correlation between shear strength and depth compared to the direct shear test,showing more pronounced depth effects.Boundary conditions and stress states are the primary factors leading to differences in shear strength between laboratory tests and in-situ field tests.During survey and design,shear strength testing methods can be appropriately selected based on project characteristics.关键词
