石河子北开发区土层剪切波速与土层深度经验关系

Empirical Relationship between Shear Wave Velocity and Soil Depth in the North Development Zone of Shihezi

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。

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.
