【摘要】 收集了石河子市北开发区已有的土层钻孔资料及有关报告。对所有的剪切波速资料进行了整理。在前人研究和数据整理、分析的基础上,分别采用线性模型、幂函数模型和一元二次多项式模型,对石河子市北开发区的土层剪切波速与土层深度关系进行了拟合。以拟合优度为评价指标给出了粉土、粉质粘土、粉砂、细砂、砾砂和圆砾的推荐模型参数。最后对结果的合理性、适用性进行了评价。更多还原

【Abstract】 The soil drilling data and reports in north development zone of Shihezi was collected, and the shear wave velocity data was analyzed. Then, linear model, power function model and a yuan quadratic polynomial model were used to fit the soil shear wave velocity and soil depth relation in the study area. Taking goodness of fit index as a factor, the model parameters of silt, silt-clay, silt and fine sand, gravel, sand and gravel are recommended. The rationality of the results and the applicability of the model are evaluated.更多还原
