| 摘 要： | 由于有很好的露头条件,作者对澜沧江小湾水电站坝肩基体裂隙的全迹长进行了现场测量,并统计了其分布规律。发现基体裂隙的全迹长分布特征与优势方位无关,全迹长主要集中分布在1～3m的范围内且在(1 0m ,2 0m ]和(2 0m ,3 0m]区间内大致服从正态分布,总体均值在2 6m左右,概率分布密度服从负指数函数关系。

| Abstract: | Authors measured full-trace length of basal joints on Xiaowan Hydroelectric Station dam shoulder rock mass on spot for very good outcrop and made statistical analysis. Based on these, authors have found that full-trace length of basal joints distribution laws are independent on predominant orientation and approximately complies with normal distribution in (1.0m,2.0m] and (2.0m,3.0m] respectively, mostly ranging between 1m and 3m. Total average is about 2.6m, probability distribution density complies with negative exponential function. |
