摘要
结合工程实例,着重对预应力管桩在施工复压桩时出现的沉桩现象进行分析,并对管桩在施工过程中采用的施工压桩力提出建议,以及对挤土管桩在终压桩后歇桩一定时间进行一次复压作为压桩工程施工结束。
This paper analyzes the phenomenon of prestressed-concrete pipe pile occurred pile sinking when it pushed down repeatedly in combination of engineering practice,makes suggestions of the push down stake forces in the construction process and the terminating condition at try again pushing down it after normal construction finish.
