近年来,在地下水位较高的软土地基的处理中,广泛地采用强夯法、振冲法以及振动挤密砂椿法等。在施工过程中定量地测定土中孔隙水压力值,对于了解加固效果、研究加固机理以及指导施工都具有十分重要的实际意义。自1979年以来,我们曾使用电阻式渗压计,先后在山西太原、潞城等地的十项地基处理工程中进行了孔隙水压力的测定。通过多次测试实践,我们对地基在各种方法处理中孔隙水压力变化规律取得了一些资料,并对国产SZ型渗压计在测量孔隙水压力中的应用问题作了初步探讨。
In recent years, in the treatment of soft ground with a high groundwater level, the dynamic compaction method, vibroflotation method, and vibratory compaction method have been widely used. Quantitatively measuring the pore water pressure in the construction process is of great practical significance for understanding the reinforcement effect, studying the reinforcement mechanism and guiding the construction. Since 1979, we have used resistance osmometers to measure the pore water pressure in ten foundation treatment projects in Taiyuan and Fucheng in Shanxi. Through several tests and practices, we have obtained some information on the law of pore water pressure change in various methods of ground treatment, and made a preliminary discussion on the application of domestic SZ type osmometer in the measurement of pore water pressure.
