摘　　要：目前常规的渗透试验是通过人工测定水温及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。基于光电和温控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测量数据的自动采集、保存及计算,很大程度提高试验数据的准确性,在实际工程中具有较强的实用性。At present, the common permeability tests are measuring water temperature and observing liquid level of variable head pipe by artificial way. The observational method will result in errors of aging & reading of test data and will not guarantee the real-time and accuracy of the test strictly. There are no differences between photoelectric & temperature control technology permeability test automatic collection system and traditional permeability test on relevant principles and procedures. The measured data have been realized firstly on automatic collecting, saving and calculation through improving test equipments and the accuracy of test data can be improved highly to provide greater practicality for practical engineering.
