Abstract

This paper aims to explore a low-strength, high-brittleness material for large-scale rockburst model tests. By adjusting the water-to-gypsum ratio, a ratio of 0.8 was found to provide ideal mechanical and non-mechanical properties, making it suitable for rockburst simulation experiments. The experimental method used was uniaxial compression testing, and common monitoring methods for rockburst tests were employed, including acoustic emission (AE) monitoring, infrared radiation temperature monitoring, and digital image correlation (DIC) techniques. The test results revealed that the acoustic emission activity, infrared radiation temperature characteristics of the simulation material when nearing fracture, and the strain field patterns captured by DIC technology all correspond with the typical failure behavior of rocks. These findings confirm the comprehensive similarity between the simulation material and natural rocks, providing a cost-effective and easily producible model material for large scale rockburst tests.

用于岩爆模拟的低强度高脆性材料的力学与非力学性能试验研究

本文旨在探索一种用于大型岩爆模型试验的低强度、高脆性材料。通过调整水膏比，发现0.8的水膏比能提供理想的力学性能和非力学性能，适合岩爆模拟实验。实验方法采用单轴压缩试验，岩爆试验常用监测方法包括声发射（AE）监测、红外辐射温度监测、数字图像相关（DIC）技术。试验结果表明，模拟材料在接近破裂时的声发射活动、红外辐射温度特征以及DIC技术捕获的应变场模式均符合岩石的典型破坏行为。这些发现证实了模拟材料与天然岩石之间的全面相似性，为大规模岩爆试验提供了一种经济有效且易于生产的模型材料。

期刊介绍： Engineering geology is defined in the statutes of the IAEG as the science devoted to the investigation, study and solution of engineering and environmental problems which may arise as the result of the interaction between geology and the works or activities of man, as well as of the prediction of and development of measures for the prevention or remediation of geological hazards. Engineering geology embraces: • the applications/implications of the geomorphology, structural geology, and hydrogeological conditions of geological formations; • the characterisation of the mineralogical, physico-geomechanical, chemical and hydraulic properties of all earth materials involved in construction, resource recovery and environmental change; • the assessment of the mechanical and hydrological behaviour of soil and rock masses; • the prediction of changes to the above properties with time; • the determination of the parameters to be considered in the stability analysis of engineering works and earth masses.
