锦屏辅助洞岩爆特征及防治措施研究

岩爆是一个世界范围内的地质灾害，目前对其准确的预报和合理的防治仍是一个难题。锦屏辅助洞为超深埋交通隧洞，在施工过程中岩爆频繁发生，严重影响施工进度，极大地威胁着施工人员和设备的安全。在全面收集与岩爆相关的地质资料的基础上，对锦屏辅助洞岩爆的类型、特征及发生规律、产生的条件与危害进行了较深入的研究，并根据岩爆产生机理和施工要求提出了相应的处理原则和防治措施，通过工程实践检验，效果良好。

Case Study on Characteristics and Prevention and Control Measures of Rock Bursts in Jinping Auxiliary Tunnel

Rock burst is a worldwide geological disaster, which is difficult to forecast and control. Due to the extremely deep cover, rock bursts occur frequently during the construction of Jinping auxiliary tunnel, which has seriously delayed the construction schedule and jeopardized the safety of the workers and equipment. The types, characteristics, occurring patterns, occurring conditions and adverse effects of rock bursts in Jinping auxiliary tunnel are studied in detail on basis of the collected geological data related to rock bursts. In addition, principles and countermeasures to prevent and control rock bursts are proposed on basis of the rock burst occurring mechanisms and construction requirements. These prevention and control principles and countermeasures have been applied in the tunnel construction and satisfactory effects have been achieved.
