深埋长大公路隧道岩爆预测及防治研究

Study on Rockburst Prediction and Prevention in Deep and Over-Length Highway Tunnel

岩爆作为深埋长大隧道在开挖后常见的一种地质灾害,极大地威胁着施工人员和设备的安全。文章在全面分析了影响岩爆发生的相关因素的基础上,结合工程实际,从影响岩爆发生的众多因素中,有针对性的选取了六个评价指标建立岩爆预测的物元模型,进行可拓学评价。并针对工程区岩爆的等级提出了相应的防治措施。通过实际分析对比表明,该模型评价结果可靠,精度较高,在岩爆预测中有良好的应用前景。

Being a kind of familiar geological hazard in deep and over - length highway tunnel, rockburst greatly threaten the safety of construction personnel and equipment. On the basis of analyzing the factors affecting rockburst and in combination with the character of the tunneling engineering, this paper has put forward the matter - element model forecasting rockburst and has evaluated the gradation of rockburst through extensions. Finally, based on the practical situation, this paper advances the prevention measure. The practical example demonstrates that the evaluating result of the model is reliable, so this method has a vast prospect in predicting rockburst.
