Discussion of Research Method of Earthquake-Preparedness and Earthquake-Resistance Problems of Tunnel through Active Fault

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.
