| Abstract: | Soil cave in karst ground is an unfavorable geologic phenomena for construction of expressway.Combing the famation characteristics of soil cave in karst ground with the characteristics of the foundation under the expressway,this paper calculated the thickness of the stable roof of the soil cave in karst ground by the effective influence depth that depends on the additional stress of the foundation under expressway and designed load on the expressway. |
