摘要
对朔黄铁路K470+760—K470+980路基病害原因予以分析,通过模型分析和工程类比法进行方案比选,确定采用双排咬合旋喷桩止水帷幕+抗滑桩病害整治方案。阐述了病害整治方案的主要工程措施及其施工工艺、施工技术要求。实践证明,所采取的整治方案占地面积小,不需额外征地,施工方便,在该砂黏土路基渗流及管涌治理中效果良好。
Through analyzing the reasons of roadbed disease in Shuozhou-Huanghuagang Railway K470 ＋ 760--K470 ＋ 980, this paper made the scheme comparison and selection by model building and engineering analogy method, determined the treatment scheme of double occlusion jet grouting pile waterproof curtain ＋ anti-sliding pile, illustrated the main engineering measures, construction technology and requirements of disease treatment measures. The practice proved that the treatment scheme adopted in this paper requires smaller area with no additional land and makes convenient construction, which has a good effect on waterproof curtain and embankment slope reinforcement of sand clay roadbed seepage and piping treatment scheme.
