| 摘 要： | 津秦铁路客运专线是指时速超过350km的高速旅客列车专用铁路。为确保列车高速、安全、舒适、平顺运行以及最大程度的减少维修工作量，客运专线要求轨道具有高平顺性。轨道是靠线下工程为基础支撑的，而路基的刚度小，沉降变形控制的难度就大，不得已对于难以控制的路段我们采取了加强软土地基处理措施。重点讲述锤击法施工预应力管桩。

| Abstract: | Tianjin-Qinhuangdao passenger dedicated line refers to the speed of more than 350km of high- speed passenger special railway. To ensure high-speed, secure, comfortable and smooth running of trains, as well as to the greatest extent reduce the maintenance workload, it is requested track of passenger dedicated line of higher ride comfort. Rail depends below the line project based support, and the foundation stiffness is small, difficulty of settlement and deformation control is large, it is difficult to control the road, so we have taken to strengthen soft soil foundation treatment measures. The hammer construction prestressed pip pile is mainly discussed in the article. |
