First, we propose two soft soil reinforcement, CFG pile and Sand Wick, stratified by slice summation method and the stability of the roadbed were checking calculation and settlement, and their technical and economic comparison, the final proposed measures to reduce the settlement after. Secondly, on the embankment slope was stable and calculation of the design of the embankment filling program, proposed to ensure measures of degree of compaction of subgrade bed. Finally, the roadbed deformation monitoring program. Design results to meet regulatory requirements related to passenger line, design and construction is reasonable.Keywords:passenger dedicated line ;soft soil foundation ;stability calculation ;post-construction settlement ;deformationmonitoring目录第 1 章绪论 ERROR: REFERENCE SOURCE NOT FOUND1.1 软土的定义、特点与工程特性 31.1.1 软土的定义及特点 31.1.2 软土的工程特征:31.2 国内外客运专线路基工程处理...
