软基路基沉降系数的影响因素分析

Analysis of Affecting Factor of Settlement Coefficient for Subgrade on Soft Soil Base

结合软基路基沉降计算的实际问题,讨论公路工程中普遍应用的一种软基路基沉降计算经验法,分析路堤填土高度、地基处理方法、填土施工速率和地质条件对沉降系数的影响,提出综合沉降系数的计算模式,对保证软基路基工程质量具有指导意义.

According to the actual problems of the experience method, commonly used in the highway settlement calculation of the subgrade on the soft soil base, an engineering, is discussed. The influence of the embankment filling height,base treatment method, filling construction rate, and geology conditions on the settlement coefficient is analyzed;and calculation model of the comprehensive settlement coefficient is presented, which has instructive meaning to ensure the subgrade engineering qualities on the soft soil base.
