汉江上游石泉水利枢纽,已完成了初步设计阶段的地质勘测工作,从壩段的选择?壩线的选择,长办第五地质勘探队,进行过1/10万至1/2千比例尺的地质测绘,岩心钻探完成7,160米,平碉、竖井完成250米。经过了一年多的勘测研究,对本枢纽工程地质的本质问题,基本查清,并选定了石泉壩段第IV壩线,作为进一步勘测设计的对象。
The upper reaches of the Hanjiang River Rock Spring Water Conservancy Project, has completed the preliminary design stage of geological surveying work, from the choice of dam section? Dam line selection, long run the fifth geological prospecting team, conducted 1/100000 to 1/2 thousand scale geology Mapping, core drilling completed 7,160 meters, flat towers, shafts completed 250 meters. After more than a year of investigation and study, the essential problems of the engineering geology of the hub were basically ascertained and the IV dam line of the Shiquanba section was selected as the object of further survey and design.
