摘要

摘要针对岩体应力测量，开发了使用环形光弹性传感器的光学偏振法、等色图案的数字摄影以及利用神经网络对其进行澄清。综述了应用光弹性法解决各种弹性和岩石压力分析问题的案例研究。通过实验室规模的实验，收集了 15000 张等色图像的数据集。机器学习算法是一个卷积神经网络，即 Inception 模块。作者建议使用井下传感器对地下矿井进行连续应力监测，并在物联网的帮助下将获得的数据整合到数字模型中。

Application of Neural Networks in Rock Mass Stress Assessment by Photoelasticity

Abstract

The optical polarization method with ring-shaped photoelastic sensors, digital photography of isochromatic patterns and their clarification using neural networks is developed for the stress measurement in rock mass. The case-studies of the photoelasticity application in solving various problems of elasticity and rock pressure analysis are reviewed. As a result of a lab-scale experiment, a data set of 15000 isochromatic images is collected. The machine learning algorithm was a convolutional neural network, the Inception module. The authors recommend using downhole sensors for the continuous stress monitoring in underground mines and integrating the obtained data in a digital model with the help of IoT.
