在岩溶地区兴建水利工程时，河谷深部岩溶的发育对库坝区的渗漏及大坝的稳定性，均有较大的影响。随着近几年工程勘察成果揭示，在北方岩溶区，同样存在河谷深部岩溶发育的问题，并且，采用过去的岩溶同步理论和深循环理论无法解释有关岩溶地质现象。因此，对岩溶区河谷深部岩溶发育规律理论的研究就显得尤为突出。本文试图运用岩溶作用动态平衡理论并结合李家庄下水库河谷区具体的地质特征对其深部岩溶发育规律进行了研究，并经工程勘察实践证明，分析结果令人十分满意，它不仅解决了以往岩溶作用理论中无法解释的岩溶地质现象等有关理论方面的问题；而且，这一分析方法在有目的地指导岩溶区前期勘察工作进而减少勘探量和后期施工处理等方面均具有十分重要的理论意义和现实意义。
In the construction of water conservancy projects in karst areas, the development of deep karst valleys has a great impact on the seepage of dam areas and dam stability. As the results of engineering survey in recent years reveal that in the karst area of northern China, there is also the problem of deep karst development in the valley, and the karst geology phenomenon can not be explained by the past karst synchronization theory and deep cycle theory. Therefore, the study on the law of karst development in the karst area is particularly prominent. This paper attempts to study the deep karst development law with the dynamic equilibrium theory of karstification and the specific geological characteristics in the valley area of Lijiazhuangxia reservoir. The result of the engineering survey proved that the analysis results are very satisfactory. It not only solved the problem of previous karst The theory can not explain the karst geology and other related theoretical issues; Moreover, this method has purposeful guidance in the karst area pre-investigation work and then reduce the amount of exploration and post-construction treatment and so has a very important theoretical significance and reality significance.
