摘要：

摘要：结合工程实例，介绍了扩建场地内预应力高强混凝土（ＰＨＣ）管桩的施工措施、施工监测方法与成果。通过在施工过程中采用超静孔隙水压力、深层土体位移与桩顶位移等监测手段，控制施工顺序与施工进度，群桩挤土效应得到有效控制，施工质量得到保证，对外围区域的影响得到控制。

Abstract:

Abstract:Combining with engineering example,this paper introduced the construction measures,the construction monitoring methods and results of prestressed high strength concrete (PHC) pipe piles in expansion areas.After some monitoring methods,such as excess pore water pressure, deep soils displacement and pile head displacement etc.were adopted in the construction process to control the construction sequence and schedule,the response of earth squeezing from group pile and the impact on external area were controlled effectively,and the construction quality was guaranteed.
