摘要
本文指出土体液化直接影响地基质量,是路桥工程的重要勘察项目之一;相较于传统的经验方法,利用标准贯入试验对土体液化进行判别更为精准、可靠.本文以此为目标,在梳理基本技术原理的基础上,重点对其数理模型进行推演与拟合,并利用工程案例对其具体流程进行了设计与应用,旨在为后续勘察工作中的地基土体判别提供依据与参考.
Abstract
This paper points out that soil liquefaction directly affects foundation quality and is one of the important investigation projects of road and bridge engineering;compared with the traditional empirical method,the standard penetration test is more accurate and reliable for the identification of soil liquefaction.With this as the goal,on the basis of sorting out the basic technology principles,this paper focuses on the mathematical model to deduce and fit,and uses engineering cases to design and apply its specific process,aiming to provide basis and reference for the identification of foundation soil liquefaction in the subsequent investigation work.
