摘　　要：针对结构面的迹长估算影响因素多、公式计算结果差异较大的问题,利用离散元UEDC软件进行随机结构面网络模拟,分析测窗尺寸与结构面迹长的相关性。以西藏地区某水电站平硐内典型结构面野外实测数据为例,计算Zhang法与Laslett法的迹长估值。结果表明:结构面迹长与测窗尺寸相关性较强;结构面迹长估算公式不同,测窗尺寸与迹长关系截然不同。窗口尺寸过小或过大时结构面迹长会出现明显偏差。Zhang法适合测窗面积较小、狭窄的位置;Laslett法适合测窗面积较大、空旷的位置。该研究为野外结构面测量窗口尺寸选取及结构面参数识别提供了参考依据。This paper is an attempt to address greater differences inherent in a for estingmating the length of a structural surface. The research involves using discrete element UEDC software for random structural plane network simulation ; analyzing the correlation between window size and trace length of structural planes due to different estimation methods; and calculating the long track valuation method and Laslett method using the field data of typical structural surface in the station in Tibet. The results show that a very strong correlation exits between the length of the structural surface and the size of the window and different formula for estimating the length means a completely different relationship between the length of the structural surface and window; too small or too large a siz^ of the window tends to produce an obvious the structural surface; and Zhang method works better for the small and narrow window area method for the large and empty space. This study may provide a reference for the size measurement and the identification of structural surface parameters.
