摘要:
安六铁路岩脚至六枝南段穿越六枝向斜，长约14.07 km，该段岩脚、对门寨、大用、地宗等隧道施工中均出现较大的涌水，对铁路施工造成较大影响，且可能会为铁路后续运营留下较大的安全隐患。本文从工程地质特征和水文地质特征两个方面对其地质机理进行研究，开展了工程地质及水文地质调查，提出了建议综合封闭洼地法、溶腔壁地下水位线痕迹法、井泉补给法及隧道内溶洞涌水量观测等多种方法来预测隧道涌水量，同时提出了在隧道来水侧设置泄水洞，并于泄水洞与正洞出水点设置集水廊道的涌水整治方案，确保隧道衬砌结构及后期铁路运营的安全。
Abstract:
Yanjiao-Liuzhi southern section of Anshun-Liupanshui railway passes through the syncline geology area in Liuzhi, with a length of about14.07 km. In this section, the large water gushing occurred in the construction of such tunnels as Yanjiao, Duimenzhai, Dayong and Dizong, which affected the railway construction seriously, and may leave great potential safety problems for the subsequent operation of the railway. This paper studies the geological mechanism from engineering geological and hydrogeological characteristics, carries out engineering geological and hydrogeological investigation, and puts forward the engineering methods to predict tunnel water inflow, such as comprehensive closed depression method, karst cavity wall groundwater level trace method, well spring supply method and observation of karst cave water inflow in the tunnel, and puts forward a water gushing treatment scheme that is to set up a drain tunnel on the water inflowing side of the tunnel and the water collecting galleries at the gushing points of the drain tunnel and the main tunnel, so as to ensure the safety of tunnel lining structure and later railway operation.
