The rapid drawing and application of joint occurrence based on fuzzy equivalence clustering

Abstract

Abstract Rock slopes are susceptible to landslides and economic losses due to the cutting effect of joint fissures. Conventional methods for investigating and analyzing the distribution and development of joint fissures have problems of low efficiency and difficulty in large-scale and accurate measurement. This article combines the fuzzy equivalent clustering method with the pole plot drawing method to develop a production rose plot drawing system through programming and carries out engineering applications. The research results indicate that the developed system can quickly achieve the drawing and analysis of structural plane orientation and rose diagram, which is simple and convenient; The dominant orientations of the three sets of joints in engineering applications are 193.11°∠ 8.25°, 112.07°∠ 83.89°, and 222.58°∠ 82.16°, with average trace lengths of 1.08 m, 0.94 m, and 1.04 m, respectively; The tendency of joint set 1 is normal distribution, and the dip angle is lognormal distribution. The occurrence distribution types of joint sets 2 and 3 are both negative exponential distribution; Three sets of rose plots of joint occurrence were also drawn, clearly indicating the spatial orientation and development degree of joints.
