摘要
地铁一般多建于地下,被地下岩土体包围,其建(构)筑物对变形的要求严格,因此基床系数在地铁设计中的作用可想而知。本文介绍了在地铁勘察中获取基床系数的几种现场试验方法,并进行了应用对比,验证了几种试验方法的有效性,对于几种方法在地铁勘察中的应用提供一点借鉴。
The subway was common built in underground.Structures and buildings on deformation of demanding things,so coefficients of subgrade is so important in metro design.This paper introduces some field test methods.The kind of the method are also helpful to obtain the coefficients of subgrade.
