岩溶发育深度问题研究现状与展望

Progress and Expectation of Research on the Depth of Karsts in Water Resources and Hydropower Engineering

岩溶发育的深度问题是岩溶学研究中一个极具挑战意义的理论难题,在水利水电工程建设中常遇到深岩溶问题。相关研究很早就有所开展,目前主要存在9种理论,分别为同步理论、深循环理论、矿液作用理论、古岩溶理论、混合溶蚀作用理论、热液作用理论、适应海平面变化理论、动态平衡理论和岩溶发育深度定量化理论。综合来看,目前的研究尚存在不少问题,进一步的研究应从碳酸盐岩溶蚀的根本机制出发,定量分析溶蚀时间、CO2含量、水流条件等因素对岩溶发育深度的影响。

The depth of karsts in water resources and hydropower engineering is very difficult to figure out and is long time a big challenge in theo-ry. In recent decades,the emergence of deep karst brings up series of geological engineering problems with the fast development of water resources and hydropower engineering. The research on depth of karsts was carried out very early and up to now there are mainly 9 kinds of theory：earlier the theory of synchronizing development,theory of deep hydrologic cycle,theory of ore solution,theory of ancient karst,theory of mixture corrosion, theory of hydrothermalism,theory of adaption to the sea level changes,modern the theory of dynamic equilibrium and last the theory of quantitative calculation. Unfortunately,there also exists many problems in these theories and the advisable research orientation should be based on the dissolu-tion mechanism of carbonates and analyze quantificational the effect of relative parameters including the time of dissolution,content of CO2 in the air,and water flow conditions,and so on.
