摘要
针对原有给水度实验仪不能直观反映地下水水位埋深及其降深对给水度影响的缺点,设计了能采用柱体法测定松散土体试样的给水度的实验仪。新设计的给水度实验仪能直观地显示出地下水水位的变化,并能反映出初始地下水水位埋深及水位降深对给水度的影响,且操作简单,易于学生理解掌握。
As the old specific water yield apparatus can not put up visually the influence of water level and its decrease depth on the specific water yield of incompact soil sample, a new apparatus is designed. The new apparatus not only can reflect the visual change of water level, the influence of water level and its decrease depth on the specific water yield,but also can be operated and understood easily by students.
