摘　　要：目前常规的渗透试验都是通过肉眼人工观察变水头管内液位高度。此观测方法易出现试验数据的时效误差和读数误差,无法严格保证试验的实时性与准确性。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,liquid level of falling head tube in the regular permeability test is observed by visual inspection totally,and this inspection method easily results to aging error and reading error of test data,which cannot ensure real-time capability and accuracy strictly.Due to the whole identity of principles and procedures between automatic collection system of permeability test based on photoelectric technology and traditional one,the automatic collection,preservation and calculation of survey data are realized initially by means of improving test equipment to strengthen the accuracy of the test data in great degree.In a word,this automatic collection system is capable of good practicability in practical engineering.
