| 摘 要： | 采用窗口法对拱坝坝肩不连续面进行描绘测量，对获取的不连续面的产状和亦长进行取样偏差校正和蒙特卡罗模拟，从而形成三维空间的不连续面网络模型。据工程要求对网络模型按一定带宽进行切割、投影、计算，由此可得到侧裂结构面的面连通率。在此基础上，可以进行坝肩岩体质量评价，为工程设计提供一定的理论依据。

| Abstract: | This paper mainly shows that discontinuities in the abutment of arch dam are measured by the means of sampling window, and orientation and trace length of discontinuities in the sampling windows are corrected and Mote-Cede simulated, thus the discontinuities' network models in 3-D space are formed. According to the project demand, the 3-D models are cut between a certain bandwidth, projected and calculated, therefore side structural planes' persistence ratio is acquired. On basic of the persistence ratio's results, rock mass quality of abutment is evaluated, and some theoretic data is offered for engineering design. |
