针对中梁山隧道K27+227~+248区段侧壁围岩破碎出现较大涌水问题，通过水文地质分析，采用瞬变电磁和探地雷达相结合的物探方法，深入分析涌水区段的涌水水源及补给通道，提出深部引流、浅层加固和深部帷幕封堵的综合治理方法。针对不同治理阶段特点，选定合适的注浆材料,取得了较好的治理效果。通过围岩变形实时监测及数值模拟分析，确定了注浆工程中围岩变形规律及其主控因素，避免了水压升高和注浆压力对围岩造成破坏，保证了注浆过程中围岩具有良好的稳定性，并成功封堵了隧道涌水。

The sources and supply passage of the water inflow in K27+227~+248 section of Zhongliangshan tunnel are analyzed on basis of hydrogeology analysis, transient electromagnetic detection and radar detection. Comprehensive treatment measures, including water releasing in deep layers, consolidation in shallow layers and deep watersealing curtains, are proposed. Proper grouting materials are selected according to the features of different grouting stages and good results are achieved. The rules and control factors of the deformation of the surrounding rock during grouting are determined by means of deformation monitoring and numerical simulation, so as to prevent the surrounding rock from being damaged by the increasing water pressure and grouting pressure. In the end, the stability of the surrounding rock during grouting is guaranteed and the water inflow is successfully sealed.
