隧洞穿过活动断裂抗震防震问题研究方法探讨
Discussion of Research Method of Earthquake-Preparedness and Earthquake-Resistance Problems of Tunnel through Active Fault
【摘要】 通过工程实例提出动态方法研究隧洞穿过活动断裂的防震抗震问题,首先通过地表探槽和钻探初步判断活动断裂与隧洞相交的宏观位置;第二根据开挖揭露的断层性状,确定最新活动断裂的出露桩号;第三再通过施工地质编录资料研究抗震防震方案。
【Abstract】 The paper proposes a dynamic method to study the earthquake-preparedness and earthquake-resistance problems by project cases.The method has three phases,the first phase is determination of the intersection location of active fault and tunnel by using trial trench and borehole;the second phase is determination of the stake number of the active fault by the characteristics revealed by excavation;the third phase is determination of the scheme of earthquake-preparedness and earthquake-resistance by construction geological logging.
