对真空、真空度、孔隙水压力、超静孔隙水压力、孔压差、负压等概念进行了阐述和澄清,分别分析了真空度、孔隙水压力现场监测的影响因素,对两者的监测仪器与方法进行了论证,并进行了沿塑料排水板深度为25 m、35 m和50 m孔压分布的现场试验。建议地下水位以上采用真空测头、地下水位以下采用孔压计进行监测,以达到事半功倍的效果,监测数据稳定可靠。

This paper describes and clarifies some concepts,such as vacuum,vacuum degree,pore water pressure,excess pore water pressure,pore water pressure difference and negative pressure etc.,respectively analyzes the influencing factors of vacuum degree and pore water pressure field detection, proves the detecting instrument and detecting method, and makes a field test of pore water pressure distribution with the plastic drainage plate’s depth of 25 m,35 m and 50 m. This paper recom-mends vacuum probe above groundwater level and pore pressure gauge under groundwater level for field detection in order to achieve half the work with double results,stable and reliable monitoring data.
