| Abstract: | In the light of a lot of landslide of the expansive soil occurred on Nanning-Youyiguan Highway in (Guangxi), a detailed geologic investigation has been adopted to analyse the landslide. The factors affecting stability of cut slope have been carefully analysed and some feasible techniques for landslide protection in expansive soil slope explored. The new method of treatment with flexible retaining wall reinforced by geotextile has been put forward for Nanning-Youyiguan Highway construction. |
