摘要
结合郑州地区典型岩土工程勘察实例,分析了以往采用理论公式计算法、参数查表法、静力触探参数计算法和载荷试验法等粉土承载力确定方法,探讨其中所存在的局限性。粉土承载力与原位测试值呈近似线性关系,而与土工试验参数相关性相对较差。提出了用原位测试法如标准贯入(SPT)和静力触探(CPT)等确定郑州地区粉土承载力的地域性经验公式。
There is a mass of silt distributing at the shallow stratum in the area of Zhengzhou,and it is important to elicit the bearing capacity of silt in project design.Some typical examples of the geotechnical reconnaissance in Zhengzhou are analyzed,determine the bearing capacity of silt.By numeration SPT-parameters and load tests,approximate linearity in original test and silt relativity are found within the dust-test parameters and the bearing capacity.Formulas of the bearing capacity are put forward by SPT and CPT for the reference in future projects.
