摘要
通过对沪宁高速公路(江苏段)拓宽工程路基实测沉降资料的分析,总结出拓宽地基沉降变形的时效特点,并在分析沉降量与填土高度关系的基础上对其进行了回归分析,这对沪宁高速公路扩建工程的路基填筑及其沉降观测数据分析具有重要的参考价值。
Through systematically analyzing of settlement data of subgrade on extension project of Huning expressway （Jiangsu section）, it conclued the aging features while settling of the subgrade.Based on analyzing the relation of settlement and depth of fill, it presents the regression fitting curve.It is very significant to guide placement in layers of subgrade and analysis of settlement observation data.
