摘要

根据伊洛河河谷平原的河滩相软土地基沉降观测结果，用指数法和双曲线法，并配合最小二乘法拟合分析，推算了地基的最终沉降量及固结参数，运用于沉降计算，发现结果比室内试验更与实际接近。对路堤填筑过程中实测沉降资料的深入分析，总结出填土高度对沉降变形的影响规律，并提出了相应的临界填土高度为2.5 m。

Abstract

This paper analyzes the site-measured settlement of the Yiluo River alluvial flat soft clay foundation in Henan province using the exponential method and the hyperbolic method; and calculates the final settlement and the consolidation parameters of the foundation. It is found that using the back-calculated permeability coefficient to calculate the settlement by FEA method is more close to the fact than the one calculated using test coefficient. Through analyzing a lot of field test data

the relationship between settlement and embankment height is summarized; and the critical embankment height 2.5 m on soft ground is obtained
