摘要
介绍了陇海线新建河车站K1330+590—K1331+150段路基病害现状、发生和发展情况,分析了病害产生的原因,针对病害情况提出了基床换填+灰土挤密桩和注浆2个处理方案,进行技术、经济比较后,选用基床换填+灰土挤密桩处理方案,提高了基床的水稳定性及承载能力,保证了路基的安全运营,可供类似工程借鉴。
The present situation,occurrence and development condition,causes of subgrade diseases of X injianhe station located in K1330 ＋ 590—K1331 ＋ 150 on Lanzhou- Lianyungang Railway were described and analyzed. The treatment schemes of subgrade bed replacement ＋ lime-soil compaction pile and grouting were put forward. After comparison the technical and the economic with the two schemes,the scheme of subgrade bed replacement ＋ lime-soil compaction pile was applied,which improved the water stability and the bearing capacity of the subgrade bed,ensured the safety operation of the subgrade. It may provide a reference for similar projects.
