软土地区铁路勘察选线及路基处理措施

Railway survey and rout selection in soft soil region and treatment measure for soft roadbed

因软土的工程性质影响路基的坚固、稳定和耐久性 ,故在软土地区进行铁路勘察选线时应分析区内软土的分布特征 ,比选线路平面方案 ,确定软土路堤填筑临界高度和设计临界高度等等。同时 ,还对作为路堤的软土底基、路基的工程处理原则。

Because the engineering properties of soft soil influence the solid, stabilization and durability of roadbed, in the railway survey and route selection in soft soil region the distribution characteristics, the critical height of roadbed accretion and critical height design should be analyzed sufficiently. At the same time the treatment principle of soft roadbed, treatment measures and matters needing attention are illustrated in detail.
