摘　　要：突泥涌水一直是地下工程建设中常见的地质灾害。对于大断面、地质条件复杂的水电站泄洪洞,其突泥涌水的防治尤为复杂。为探究大断面泄洪洞突泥涌水的治理措施,以大岗山水电站泄洪洞为工程背景,通过现场物探检测及室内力学性能试验综合分析工程地质状况。针对泄洪洞内存在的突泥涌水风险,结合地质条件分析,给出需重点关注的防治措施。对于施工过程中可能出现的突泥涌水等特殊情况,从封堵、回填等方面开展有针对性的治理技术研究,总结得到一套有效的突泥涌水封堵技术方案。Burst mud and gushing water has always been a common geological disaster in underground engineering construction. For large-section flood-discharge tunnels with complex geological conditions, the prevention and control of burst mud and gushing water is particularly complicated. To explore the treatment measures, with flood-discharge tunnel of Dagangshan Hydropower Station as the engineering background, the engineering geological conditions are comprehensively analyzed through on-site geophysical detection and indoor mechanical performance tests. Aiming at the risk of burst mud and gushing water in flood-discharge tunnel, the analysis of geological conditions is conducted, and the prevention measures that need to be focused are given. For special situations such as burst mud and gushing water that may occur during the construction process, the targeted treatment technology research from the aspects of plugging and backfilling is carried out, and a set of effective plugging techniques of burst mud and gushing water are investigated.
