Abstract

The invention relates to a fully-automatic Darcy law experiment system which is characterized by comprising a water supply system, an infiltration system and a data acquisition and processing system; the work of the fully-automatic Darcy law experiment system is realized through the steps of initial numerical measurement, water pump water supply, water infiltration, data acquisition, data calculation and the like; through the automatic whole-process control Darcy law experiment system, the numerical measurement accuracy and precision are greatly improved, and the experiment efficiency of the Darcy law experiment system is improved.

Description

technical field [0001] The invention relates to the field of soil experiments, in particular to a fully automatic Darcy's law experiment system. Background technique [0002] Darcy's law is also known as the law of penetration, the formula is: [0003] Q=KFI or [0004] It means that the permeation flow through the sample is directly proportional to the cross-sectional area of ​​the sample and the head difference of the pressure measuring tube at both ends of the sample, and inversely proportional to the permeation path of the sample, and the proportional coefficient is K (permeability coefficient). Darcy's law is the theoretical basis for analyzing dam seepage calculation and groundwater seepage calculation. Darcy's law experimental instrument is an experimental instrument specially used to verify Darcy's law and determine the permeability coefficient. At present, a kind of Darcy's law experimental instrument commonly used at home and abroad, its method is: the experim...
