【摘要】 针对溪洛渡水电站坝基玄武岩内裂隙延伸短小、贯通性差的特点,提出了基于结构体块径指标的断续节理岩体的岩体结构类型划分方法——标准网格比对法;以距开挖轮廓线的相对距离为控制坐标,提出了简化的摄影解译技术。将标准网格比对法和简化后的摄影解译技术应用到溪洛渡水电站坝基玄武岩岩体结构类型划分中,取得了较好的效果,并具有方便快捷的优点。更多还原

【Abstract】 As the fissures in the dam basalt of Xiluodu project is shorter and poor linking,a method which called"Standard Grid Comparison Method"for classification of rock mass structure is presented based on the rock mass size index,and a simplified photographic interpretation technique is proposed after taking the relative distance of digging contour as control coordinates.The application of Standard Grid Comparison Method in Xiluodu project has achieved a good result.更多还原
