山西省中条山喀斯特发育特征及兴建水库工程可行性初探

A PRELIMINARY DISCUSSION ON THE CHARACTERISTICS OF DEVELOPMENT OF KARST IN ZHONGTIAOSHAN AREA OF SHANXI PROVINCE

中条山分布着大片的碳酸盐岩层。年降水量７４０ｍｍ，年平均气温１４℃。气候条件和多次的构造运动，控制和决定了中条山喀斯特的发育程度、地貌景观，以及岩溶地下水的赋存和运移特征。在水利水电建设中，渗漏成了非常突出的工程地质问题，对坝址选择产生了一定的影响。

Carbonate rocks are widely distributed in Zhongtiaoshan area, where annual precipitation is 740 mm, mean annual temperature is 14℃. The climatic conditions and multiple tectonic movements controlled anddetermined the development of karst, geomorphologic landscape, and theoccurrence and transportation of ground water through karst. Here thepercolation becomes an outstanding engineering geological problem inwater conservancy and hydropower construction and has a certaininfluence on dam sitting.
