摘要
讨论渗流监测中测压管的设计与施工的某些问题，认为测压管进水段的长度应根据具体工程、部位和监测内容而定，不必硬性规定；测压管的管径大小不会产生管内水位对周围岩土中地下水位的滞后，不会影响监测成果；测压管中水位对库水位的滞后，取决于渗径和岩土的渗透性能，与测压管的管径无关。
This paper analyses the seepage law of ground water in rock and soil. It is pointed out that the length of the entrance section and the diameter of the piezometric tube should be determined according to the project characteristics and monitoring purpose.
