摘要
根据杭州地区大量实际工程的勘察资料,通过采用土层剖面随机场模型,把土性参数的点变异性和空间变异性联系起来,对几个典型土层强度指标的空间概率特征进行了统计分析,得出了强度指标相关距离和空间变异系数的变化规律。另外,还对杭州地区几个土层强度指标三轴实验和直剪实验的差异性和相关性进行了实验研究。
Based on the engineering geologic investigation reports of many important buildings in Hangzhou area, point variability and spatial variability of soil property parameters, are associated by means of stochastic field model of soil profile. Then some variation laws of the correlative distance and spatial variability coefficient are gained by statistic analysis of shear strength indexes of several typical stratums. Besides, the difference and correlation between the strength indexes of direct shear and triaxial compression tests were studied.
