摘　　要：如何预测坝址区未揭露岩体中裂隙的分布是一个难点。通过采用全开挖面调查的方法,在该水库重要坝段已揭露裂隙精细描述的基础上进行统计分析,分别求解出裂隙平均间距和平均迹长符合的概率模型,进而找出两者之间符合的一般规律,达到通过揭露裂隙来预测未揭露岩体的裂隙分布,为大坝的施工建设提供具体的预测。It is a difficulty that how to forecast the regularities of unexposed discontinuities. Based on the precise measure of all the exposed discontinuities on the reservoir dam, the authors find the regularity of both the trace length and space length of discontinuities. According to the conclusion, we can afford guidance to the construction of the reservoir dam.
