岩体完整性是影响岩体稳定性和力学性能的重要因素,在工程勘察中,对岩体完整性影响最大因素,即岩体破碎区域的统计、描述、分析和评价是一项必不可少的内容。在摄影测量原理的基础上,利用图像处理和分析的方法进行了破碎区域的提取、划分和进一步分析。利用传统的方法对图像进行前期处理,然后提出“破碎概率”的概念并根据该值对图像进行滤波处理,剔除干扰数据,在此基础上提出用人工方法进行区域划分,采用最小二乘法得出破碎区域的等效倾角、长度和宽度,最后通过工程应用验证了该方法的可行性并提出了其存在的不足和需要改进的地方。
The integrity of rock mass is an important factor affecting the stability and mechanical properties of rock mass. In engineering investigation, the most important factor affecting the integrity of rock mass is the statistical, description, analysis and evaluation of rock mass crushing area Content. Based on the principle of photogrammetry, the method of image processing and analysis was used to extract, divide and further analyze the broken area. The traditional method is used to pre-process the image. Then the concept of “broken probability” is put forward and the image is filtered according to the value. The interference data is removed. On this basis, the method of dividing the area by artificial method is proposed. The equivalent dip angle, length and width of the broken area are obtained. Finally, the feasibility of the method is verified by engineering application and the existing problems and the improvements are put forward.
