| 摘 要： | 面波法是一种新的浅层地球物理勘探方法,由于它方便快捷、成本低、效率高,在岩土工程勘察中的应用越来越广泛,但在定量评价地基土力学强度方面的应用和研究相对较少。本文利用统计学的原理,研究了卵石土地基动力触探击数和剪切波速的关系,研究发现,二者之间具有良好的指数函数相关关系,通过这种指数函数回归关系可以应用面波法定量地评价卵石土地基的承载力。

| Abstract: | The method of surface wave velocity is a method of geophysical exploration for shallow formations,which is widely used in geotechnical engineering because of its convenience,rapidity,high efficiency and low cost,but it rarely used in the quantificational evaluation of mechanical strength of soils.In this paper,the exponential function correlation between the blow counts of dynamic penetration test and the velocity of shear waves for cobble soil is studied,which can be used to determine the bearing capacity of cobble soils. |
