Earth dam seepage observation method, the current domestic commonly used piezometric tube to observe. Traditional piezometers are usually made of brown leather and linen for water filtration. Such piezometers have the problems of high cost, short service life, troublesome construction, poor filtration performance and easy to cause human errors. In response to these problems, we conducted a new study, with geotextile fabric instead of brown, linen, as the piezometric tube ...
