岩体结构信息的采集处理研究

Research of collecting information of rock mass structure

岩体结构理论指出,结构面是岩体的构成因素之一,它的空间展布信息是进行岩体结构类型划分、岩体质量评价所需的最基础的资料。当前最为广泛采用的结构面空间分布信息采集方法是人工精测法,应用该法室外工作量大,而且工作环境对采集数据的精度、效率影响很大。论文介绍了依据计算机视觉理论,针对金沙江下游某水电站坝前右岸滩地结构面信息采集的实际情况而开发的岩体结构信息采集及处理程序,以数码摄像机快速高效的拍摄滩地,在室内解析岩体数码图像的信息,并应用已开发的可沿任意方向进行结构面切割的程序处理结构面信息,获得结构面间距、迹长、单位面积裂隙总条数等岩体结构类型划分指标。经现场实测、比对,应用该法不但可提高工作效率、减少误差,而且大大地改善了工作环境,所得结果较为可信,为坝基岩体质量研究提供了详实的基础资料。

The measuring and statistical work of joints is one of the basis in studying rock mass quality and rock mass structure.Traditional statistical method involves much work and low efficiency in field. In this paper, according to the principle of Computer Optic,a kind of method is proposed to get the features of rock mass structure by dealing with digital images taken at the rightshore of the Jingsha River in the computer.The joint corresponding program is also introduced. Through this method,the error can be reduced in great deal,meanwhile the working condition in the field is improved in great extent.
