| 摘 要： | 通过对河南焦作至巩义黄河公路大桥连接线工程持续两年多的观测，获得了有关数据两万多个。利用这些观测数据，引入路堤断面中点和两侧坡脚地基表面3点沉降的方差这一统计学指标，详细分析了地质结构，填筑速率、填筑高度以及硬壳层等因素对软基不均匀沉降的影响，得到了一些有意义的结论。这些结论对于加深软基不均匀沉降规律的研究具有积极意义。

| Abstract: | More than two thousands data were obtained by the observations posted to the projects of Jiaozuo-Gongyi Yellow River bridge joint road. Variance index of the settlements of soft clay subgrade was inducted to analyze the asymmetry settlement rules under the influence of depth of fill, fill speed, geologic types of soft clay etc. Some conclusions were drawn; and these can be used in the research of soft clay. |

| Keywords: | soft clay foundation asymmetry settlement field test |
