针对沪西变电站地基处理工程所具有的桩型多、桩数多、临近运行变电站、工序复杂、工期长等施工特点，从桩基施工监测的必要性、监测项目、监测要求、实际监测记录及针对性控制措施等方面进行了详细论述，阐述了超孔隙水压力、深层土体位移、桩顶位移、地面位移等桩基施工监测项目的量化方法。

Huxi Substation Foundation Project is featured by many pile types, a number of piles, being close to an operating substation, complicated process and long duration. This paper discussed in detail the necessity of pile foundation construction monitoring, monitoring items, monitoring requirements, the actual records of monitoring and the corresponding control measures, as well as described the monitoring items such as excess pore water pressure, deep soil displacement and pile top displacement and ground displacement, which could provide guidance to the pile construction.
