节理化岩体结构面分布密度的确定方法及其应用

目前众多的科研与工程人员都采用岩体结构面统计分析和计算机随机模拟的手段来研究节理化岩体的工程性质,然而许多人忽略了岩体结构面密度具各向异性特征以及野外实际测量条件与理论情况还存在一定的差异,在计算中采用的结构面密度值不尽合理,常常导致分析结论有失偏颇。针对这一情况,充分考虑了结构面“方向校正”和“迹长截尾校正”,并根据野外测线长度进行加权平均,提出了一套较为系统合理的结构面分布密度计算方法,并将其应用于工程实际,取得了较好的结果。

THE TECHNIQUE AND APPLICATION OF ASSESSING THE DISTRBUTING DENSITY OF STRUCTURES IN ROCK MASS

A lot of researchers and engineers began to explore the engineering characters of rock mass, on the base of statistical analyzing and computer simulating to the structure of rock mass. But, many of them neglect the anisotropy of the distributions density of the structure of rock mass and adopt incorrect value of distributing density of these structures in their analyzing, which often leads to absurd conclusions. To this question, a systemic and more appropriate theory was developed in this paper, by well considering the effects of "direction error revising","length truncation error revising" and the weights of the length of scan lines, in order to acquire proper distributing density of rock structures. The presented research results proved to be reasonable by a successful application in an actual engineering project.
