| Abstract: | The research present state of engineering geology of karst cave were summarized from two angles which includes measuring and testing technique and analytical method. The evaluation on roof stability of karst cave was the key problem when the express highway, railway, bridge, tunnel and buildings were built on karst area. The evaluation method on roof stability of karst cave were analyzed using qualitative analysis, semi quantitative analysis and quantitative analysis. The next direction of research was that investigating engineering geology and hydrological geology utilize suitable physical logging, emphasizing laboratory and site physico mechanical testing, similar model testing and numerical analysis, coupling the actions of fracture water and atmosphere circumstance. |
