摘　　要：首先,通过室内模型试验认为,一字形塑料排水板在换算成等效直径的砂井时换算系数宜为0.85～0.9.然后,对等效直径的各种研究方法进行了讨论,并给出了排水板等效直径的定义.Based on laboratory model tests, it is considered to be suitable to select a conversion coefficient 0.85～0.9 to convert the band shaped prefabricated drains into sand wells with an equivalent diameter. Some issues existing in the study on the equivalent diameter of prefabricated drains are analyzed, and a definition for the equivalent diameter of prefabricated drains is given.
