基于光电技术的渗透试验自动采集系统

Permeability test automatic collection system based on photoelectric technology

目前,常规的渗透试验都是通过人工肉眼观察变水头管内液位高度,这容易导致试验数据的时效误差和读数误差。基于光电技术的渗透试验自动采集系统与传统的渗透试验原理和步骤完全相同,通过改进试验设备首次实现了测量数据的自动采集、保存及计算,很大程度提高了试验数据的准确性,在实际工程实践中具有较强的实用性。

At present, the conventional permeability test is that the liquid height of the variable head tube is observed by the human eyes, which easily leads to the prescription errors and reading errors of the test data. The principles and procedures is identical between the permeability test automatic collection system based on photoelectric technology and the conventional permeability test, then the automatic collection, storage and compute of measurement data are realized firstly by improving the test equipment, which improve largely the accuracy of the test data and has the strong practicability in the actual engineering practice.
