摘要
Abstract
Ballastless track is usually laid inside the high-speed railway tunnel. Because of the great influence of water pressure on the foundation of the tunnel, the track tends to uplift, characterized by outburst occurrence,serious consequence and difficult remediation. In order to better solve the impact of track uplift,this paper analyzes the causes of the problems by the combined means of field investigation, drilling inspection and numerical simulation. The main cause is the action of water pressure. According to the results of field research, a comprehensive rectification scheme is proposed, involving the anchor bolt grouting anchorage in the tunnel bottom+reinforcement of steel bars in drill holes of track slabs. And preventive techniques are put forward to provide reference for engineering disaster treatment in similar projects.关键词
