作为地基的模型,载荷试验常被用作确定地基承载力的一种重要原位测试手段,但在实用中往往受到试验周期长及加荷条件麻烦而不可能对每个建筑场地都进行,而静力触探试验则较为方便易行。因此,笔者在省内选择了有代表性的5000cm~2方形载荷板的试验资料与静力触探试验资料进行对比,用数理统计方法建立静力触探比贯入阻力Ps与载荷试验的界限荷载Pnp的相关关系,借此关系可用Ps值推算Pnp。
As a model of the foundation, the load test is often used as an important in-situ measurement method to determine the bearing capacity of the foundation. However, in practice, the test cycle is long and the loading conditions are inconvenient, and it is not possible to perform every construction site. Cone penetration testing is more convenient. Therefore, the author chose a representative 5000cm~2 square load plate in the province to compare the test data with the static penetrating test data, and establish the boundary between the static penetration ratio Ps and the load test using the mathematical statistics method. The correlation of the load Pnp, whereby the Ps value can be used to estimate Pnp.
