摘要
高速铁路对路基的工后沉降提出了严格的要求 ,而现有的软土地基沉降计算方法难以满足设计要求 .通过对软土厚度 10m、路基长度 6 5m和高度 4 .5m的路基原位试验 ,分析了塑料排水板处理软土、堆载预压对地基工后沉降的影响 .
Settlement of high-speed railway subgrade after construction is strictly limited,but settlement calculation methods of soft soil are not satisfactory for design.In-situ test of subgrade with thickness of 10 m soft soil ground,length of 65 m and height of 4.5 m is studied.Soil settlement after construction by using prefabricated strip drains and preloading method is analysed.This will provide a basis for the design of high-speed railway subgrade on soft soil.
