摘要
以低液限粘土为例,依据双桥静力触探试验成果,通过多元回归方法获得了干密度与锥尖阻力、摩阻比的函数关系。检验结果表明,所建的关系式回归效果明显,相关系数为0.97。以某堤防土方试验数据进行验证,结果表明干密度理论计算值与实测值的误差在允许范围内,验证了所给公式的合理性。
Taking the low liquid limit clay for an example,based on the double cone penetration test,the functional relationship between dry density and cone trip resistance and friction ratio was obtained by using multiple regression method.The test results show that the relational regression is effective and the correlation coefficient is 0.97.The calculated data were verified by the earthwork test data of an embankment.The results show that the error between the theoretical calculation value and the measured value of soil dry density is within the allowable range,and the rationality of the formula is verified.
