摘    要:为保障九岭山隧道施工安全,准确预测掌子面前方未开挖段的岩爆发生状况,采用理论与实测相结合研究手段,对隧道的岩爆发生状况进行了预测。通过岩爆预测并结合已开挖段的岩爆发生情况,得出卢森、王元汉、王兰生判据的结论更适合九岭山隧道的实际情况。基于应力解除法的二次应力测试和基于应力判据法的岩爆预测准确性也得到了验证,得出九岭山隧道未开挖段DK1689+140~+450为中等岩爆区域。

关 键 词:隧道工程  岩爆预测  应力解除法  应力判据  点荷载测试

Study on Rock Burst Prediction during Construction of Jiuling Mountain Tunnel on Menghua Railway
Abstract:For the sake of safety of Jiuling Mountain Tunnel and to accurately predict the rock burst that may happen in the sections unexcavated before heading, the research means combining theory and measurement were used. Based on the rock burst prediction and the actual situation of rock burst happened in the excavated sections, it was concluded that Russense Criterion, Wang Yuanhan Criterion and Wang Lansheng Criterion are applicable to Jiuling Mountain Tunnel, and with secondary stress test based on stress relief method, the accuracy of rock burst prediction based on stress criterion method was verified. The unexcavated section DK1689+140~+450 of Jiuling Mountain Tunnel was found to be moderate rock burst zone.
