| 摘 要： | 以鹞子岩（山岭）隧道区域地质及基础勘察设计资料为依据，选取因素评价指标，通过综合超前地质预测预报与实际开挖情况相结合的方法，建立了隧道围岩动态化分级体系；对BQ法围岩分级进一步优化及动态调整。工程实践表明:该动态分级体系对掌子面前方围岩情况实现精准预测分级有较强的实用性。

Research on Dynamic Classification of Surrounding Rock in Mountain Tunnel |
| |
| Abstract: | Bases on the regional geology and basic survey and design data of the mountain tunnel (Erziyan), factor evaluation indicators are selected. The dynamic classification system of tunnel surrounding rock is established by combining advanced geological forecast and actual excavation, and the grading of surrounding rock of BQ method is further optimized and dynamically adjusted. The engineering practice shows that the dynamic grading system of surrounding rock has strong practicability for accurately predicting and grading surrounding rock conditions in front of the tunnel face. |
