【摘要】 在软土地区修建高速公路,根据观测到的地面沉降-时间过程线推算地基的最终沉降量的实用方法十分重要。本文介绍了目前常用的推算方法有双曲线法、沉降速率法、三点法,并使用这些方法对某高速公路路堤的最终沉降量进行推算。根据推算结果比较各方法的适用性、可靠性。更多还原

【Abstract】 Constructing expressway in soft soil area,the practical methods for calculating the final settlement of groundwork through the observed settlement-time process curve of ground are very important This paper introduces several common-used calculation methods such as the hyperbolic method,the settling speed method and the three-point method,which can all be utilized to calculate the final settlement of embankment in a expressway project.At last,this paper compares the applicability and security of each method depending on the calculation results.更多还原
