摘要:
随着我国高速铁路的规划、建设逐步向寒区扩展，路基工程中势必要面对各类的工程冻害问题.基于控制轨面变形出发，在以往的工程实践中，主要集中在路基粗颗粒填料中细粒组分(<0.075 mm)的含量以及含水率对土体冻胀率的影响.考虑到受击实功影响的压实度是控制路基施工质量的重要因素之一，因此试验中引入击实功这一因素，探讨了击实功与冻胀率之间的关系，并通过对不同击实功下不同含水率和细粒含量的粗颗粒填料在不补水条件下的冻胀试验，分析得到路基粗颗粒土的击实功对冻胀率的影响.结果表明：标准击实条件下的冻胀率最大，欠击实和超击实条件下的冻胀率居中，不击实条件下的冻胀率最小；随着含水率的增大，粗颗粒土体的冻胀率也随之增大；但随着细粒含量的增大，粗颗粒土体的冻胀率反而降低，并据此提出了粗颗粒土体中细颗粒组分单位面积吸附水质量分布的一种解释.
Abstract:
Frost damage in subgrade engineering is a common problem during planning and construction of high-speed railway which gradually extends into cold regions. In the past years, many studies have investigated the influence of fine content (D＜0.075 mm) and moisture content on frost-heave ratio in coarse-grained filling materials，which based on restrictions of rail surface deformation. It is established that compaction degree is an important standard of subgrade construction and is completely determined by compaction energy. Few authors had considered this factor in the subgrade construction in cold region. Thus, the effect of compaction energy was considered in this study. Frost-heave tests with different fine content and moisture content with non-water supply under different compaction energy conditions were carried out to determine the relationships between compaction energy and frost-heave ratio. Results showed that frost-heave ratio was the maximum in the standard compaction energy test, minimum in the non-compaction energy test, and median in the insufficient compaction energy and over compaction energy tests. High moisture content meant large frost-heave ratio. Surprisingly, frost-heave ratio decreased with the increase of fine content. An explanation of coefficient adsorption of water quality per unit area was also setup.
