摘　　要：针对混凝土耐久性试验,为了满足多因素耦合作用下加载的要求,基于国内外现有加载装置的优缺点,设计制作了运用于多因素耦合作用下离子侵蚀混凝土试验用的加载装置,并进行了相关性能的测试。结果表明,该新型加载装置具有加载精度高、应力损失小、操作简单、制作成本低、可用于批量试验等优点。该装置获得国家专利,可供混凝土耐久性研究人员参考使用。According to the durability test of concrete, and in order to meet the requirements of stress loading affected on concrete by multi coupling factors, a new loading device which takes account of ion e- rosion concrete under multi coupling factors was designed, made, and used to test the durability of con- crete. The new device adopted the advantages and avoided the disadvantages of existing devices in China and foreign countries. The test results show that the new device has many excellent characteristics such as high loading accuracy, small stress losses, simplicity of operation, low cost and can be used for lots of test. The new device has gained national patent certificate of China, and may provide references for the research of concrete durability
