碎石桩处理下软土路基沉降变形研究

Research on Soft Soil Roadbed Settlement Deformation in Gravel Pile Treatment

基于遂(宁)—资(阳)—眉(山)高速公路软土路基碎石桩处理工程实例,以碎石桩处理软土路基理论为依据,结合路基变形监测数据对路基的沉降、侧向变形之间的关系及变化规律进行定量和定性分析,得出软土沉降、侧向位移与填筑高度之间的关系,对类似工程的设计与施工起到一定的参考和指导作用。

Based on the gravel pile treatment foundation engineering project of Sui （ning ）-Zi （yang ）-Mei （shan）superhighway,the theory of gravel pile treatment in soft soil roadbed and the roadbed deformation monitoring data,this article carrys on the qualitative and quantitative analysis of the roadbed settlement and the relation of lateral deformation as well as its ange rules and then obtains the relationship of the soft soil settlement,lateral displacement and the filling height,which provides a certain guidance and reference for the design and construction of similar projects.
