平板载荷试验检测广州地区典型土层地基承载力特征值的研究
Research on the Characteristic Value of Bearing Capacity of Typical Soil Foundation in Guangzhou by Plate Load Test
摘要
Abstract
According to the physical and mechanical property indicators of typical soil layers in Guangzhou in relevant references,and by using the inverse calculation of foundation bearing capacity formula,this paper determined some shear strength indicators,calculated the settlement of 84 groups of soil layer models,and obtained the settlement s of square plates with different width b under the corresponding load of foundation bearing capacity characteristic value and the distribution law of s/b value in various soil layers.The results show that when the width of the square pressing plate is in the range of 0.707 m to 2 m,the calculated value of the relative deformation value s/b corresponding to the characteristic value of the foundation bearing capacity has no obvious change.The calculated value of s/b of low compressibility soil of typical soil layers in Guangzhou is 0.005～0.010,the average value is 0.008,the standard deviation is 0.001,and the dispersion coefficient is 0.125.The calculated value of s/b of medium compressibility soil in the typical soil layers in Guangzhou is 0.008-0.021,the average value is 0.016,the standard deviation is 0.004,and the dispersion coefficient is 0.250.关键词
