隧道施工主要通过结合超前地质预报,根据现场施工情况,坚持动态设计,动态施工。本文通过对季家坡隧道遇到的瓦斯不良地段地质及瓦斯情况分析,有效结合超前地质预报及超前钻孔手段,并根据现场实际情况有效调整支护参数,加强监控量测,加强安全管理,最终顺利地通过不良地质段,在施工中不断总结经验,供类似工程施工参考。 Tunnel construction mainly through the combination of advanced geological prediction, according to the site construction, adhere to the dynamic design, dynamic construction. Based on the analysis of the geological and gas conditions in the gas-poor section encountered in the Jijiapo Tunnel, this paper combines the advanced geological prediction with the advanced drilling method effectively and effectively adjusts the support parameters according to the actual situation in the field, strengthens the monitoring and measurement, strengthens the safety management, Finally successfully passed the bad geological section, constantly sum up experience in construction for reference for similar projects.
