摘要:
深部隧道岩爆已成为影响工程安全施工的重要危险源,室内模拟实验是研究深部岩爆问题的重要手段之一。为研究岩爆倾向性较高的模型,使用石英砂、水泥、石膏等材料进行配置,设计正交试验方案,进行力学试验,依据岩爆倾向性指数及脆性指标,利用试验试件参数进行有限元模拟,对室内试验进行验证。结果表明,配比为石英砂55%、石膏水泥比2.5:1、松香4%、水含量23.3%的2号试件具有比其他两组试件更强的脆性,配比为石英砂70%、石膏水泥比1.5:1、松香3.5%、水含量20.6%的16 号试件具有更强的岩爆倾向性。以2 号试件为例进行数值模拟,两者数据拟合较好,模拟现象与试验现象相吻合,可为岩爆室内试验及模拟提供参考。
Abstract:
Rockburst in deep tunnels has become an important source of danger that affects the safety of engineering construction. Indoor simulation experiments are one of the important means to study deep rockburst problems. In order to study the model with high rockburst tendency, quartz sand, cement, gypsum and other materials were used for configuration, and an orthogonal test plan was designed, and a mechanical test was carried out. According to the rock burst tendency index and brittleness index, a finite element simulation was carried out by using the test piece parameters to verify the laboratory test. Results show that test piece No.2 with a ratio of 55% quartz sand, a gypsum-cement ratio of 2.5∶1, 4% rosin and a water content of 23.3% has stronger brittleness than the other two groups of specimens, and test piece No.16 with the ratio of quartz sand is 70%, 1.5∶1 gypsum-cement ratio, 3.5% rosin, 20.6% water content has a stronger rockburst tendency. Taking the test piece No.2 as an example, the numerical simulation is carried out. The data of the two are well fitted, and the simulated phenomenon is consistent with the experimental phenomenon, which can provide a reference for the rockburst laboratory test and simulation.
