摘要
从定性、半定量和定量分析三个方面对岩溶洞穴顶板稳定性评价方法进行了讨论。指出选用合适的物探手段进行调查,开展室内和现场的岩体物理力学试验,特别是加强相似模型试验和数值分析研究,综合考虑裂隙水、大气环境共同作用,是综合评价岩溶洞穴稳定性的发展方向。
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.
