摘　　要：采用新型水位管法测试真空预压条件下地下水位,通过常规水位管法和新型水位管法的现场对比试验,验证了新型水位管法的可行性,并结合现场采集的其他数据进行系统分析,探寻表面沉降、真空度和孔隙水压力与地下水位变化之间的内在联系,总结真空预压过程中地下水位的变化规律,并对地下水位的变化机理进行分析。The new water gage method is used to test groundwater level under vacuum preloading. Through the contrast ofconventional water gage method and new water gage method in the field tests, we verified the feasibility of the new water gagemethod. The system analysis is carried with other field collected data to understand the inner link between underground waterlevel and surface settlement, vacuum degree and pore water pressure. The variation law of the groundwater level under vacuumpreloading is summarized, and the change mechanism of the groundwater level is analyzed.
