为对火成岩隧道工程的涌突水进行准确的预测预报,从岩性、岩相、裂隙、构造和成岩作用等方面,分析影响火成岩储水空间和性能的因数。在此基础上,结合实际涌突水情况,分析泥巴山隧道火成岩储水性影响因素和储水特征。发现其储水性主要受构造作用影响,储水部位为构造裂隙发育地段,但在其它因素的影响下,岩体储水性发生变化,导致涌突水位置、涌水量和涌水类型相应的变化。
In order to accurately predict and predict the water inrush in igneous tunnel project, the factors affecting the space and performance of igneous reservoir are analyzed from lithology, lithofacies, fissures, tectonics and diagenesis. On this basis, combined with the actual situation of water inrush, this paper analyzes the influencing factors and storage characteristics of igneous rocks in mud tunnel. It is found that the water storage is mainly affected by the tectonism. The water storage site is the site where tectonic fissures develop. However, under the influence of other factors, the water storage of the rock mass changes, resulting in the corresponding changes in water inrush position, water inflow and gushing water types.
