土的渗透系数是土坝等工程设计中必不可少的基本数据,它是由变水头渗透仪试验得来的。过去试验时由人工操作,隔一定时间读一个测压管水位数,连续几次。经计算测得,在试验中,需有专人管理,且只能逐个进行,计算量多,工作低。为此我们研制了电子自控渗透仪,不需专人管理,读数精确,计算简化,从几个至十几个土样可同时进行,节省劳力与
The permeability coefficient of soil is an indispensable basic data for engineering design of earth dams and it is obtained from a variable head permeameter. In the past, the test was performed manually, and the water level of a piezometer was read several times in succession. According to the calculations, special personnel are required to manage the tests and they can only be performed one by one. The amount of calculation is large and the work is low. To this end, we have developed electronically controlled permeameters that do not require special management, accurate readings, and simplified calculations. From a few to a dozen soil samples can be performed at the same time, saving labor and
