| 摘 要： | 通过对沪昆高速公路区域工程水文地质条件、岩溶发育特征进行分析,表明路基岩溶病害产生的原因是由于该区域地下水位快速下降导致不同性质的岩溶覆盖层塌陷引起的,为了达到治理效果,要根据岩溶发育特征的不同,比选不同的治理方案,采用合理的措施对路基下岩溶进行治理。

| Abstract: | The analysis on hydrogeological condition and karst development of Shanghai-kunming expressway region demonstrate that： there are four concentrated areas of karst development in this section, subgrade diseases are caused by the fast decline of ground water levels which leads to different subsidences in karst overburden. In order to improve this condition, we should compare different kinds of treatment scheme in accord- ance with the features of karst development and take reasonable actions to improve the karst condition under the subgrade. |
