路堤荷载作用下软土硬壳层地基沉降计算

Foundation Settlement Calculation of Hard Shell Course in Soft Soil under Embankment Load

在工程设计中遇到软土硬壳地基时,一般是进行软土地基加固处理,这样一来就破坏了硬壳层的整体性,延长了工期,增加了造价。对路堤下软土硬壳层地基沉降计算方法进行研究,利用修正后的公式计算试验监测断面的沉降量,并与现场监测数据进行比较,目的是分析直接在软土硬壳层上填筑的路堤的沉降变化。

During the foundation construction of hard shell in soft soil in engineering design,the reinforcement treatment of soft soil foundation is usually performed,which destroys the integrity of hard shell course,prolongs the construction period and increases the cost.The research on the foundation settlement calculation method of hard shell course in soft soil under embankment is made.The settlement of test monitoring section is calculated by using the revised formula and compared with the field monitoring data.The purpose is to analyze the settlement change of embankment directly filled on hard shell course in soft soil.
