摘要:
文章针对南昆铁路南宁至那厘段红黏土地面开裂问题深入分析,得出该地区地面开裂是红黏土内在特性在特定气候、植被、地理环境的作用下发生的,不是岩溶塌陷前奏。采取加强排水,在路基基底换填砂卵石垫层,在坡脚设置护脚墙,在坡脚设挡土墙的工程措施,按原方案继续开展施工,取得良好效果。
Abstract:
In line with the deep analysis on the cracking of red clay ground in the section of Nanning-Nali of NanningKunming railway, it is concluded that it is because the inherent characteristics of red clay change by the factors of climate, vegetation and geographic environment, but the omen of karst collapse. Engineering measures are adopted, like strengthening drainage, refilling sandy pebble cushion on the base of subgrade, setting protection wall on the base of slope and setting retaining wall on the toe. Construction is carried on according to the original plan and good results are obtained.
