桩基清除是港口、海洋工程的重要组成部分,影响桩基清除的因素主要有桩基类型、土的工程性质、桩基尺寸、成桩工艺等。目前为止已经形成了震动拔桩、高压旋喷震动拔桩、震动沉管高压水射流拔桩和爆破拔桩等多种方法。其中以震动拔桩和震动沉管高压水射流拔桩应用最为广泛。随着海洋工程的快速发展,需要新的拔桩方法和工艺以满足工程需求。

As one of important parts in port and ocean engineering,the pile extraction may be affected by the parameters such as the type of pile,engineering property of soil,pile dimensions,and pile construction technology. Until now,the following pile extraction methods has been developed,i.e. the vibration method,high pressure jet grouting vibration method,vibrating sinking-pipe high pressure water jet method and blasting method. Among them, the vibration method and vibrating sinking-pipe high pressure water jet method are widely applied. New pile extraction method and technology are required along with quick development of ocean engineering.
