摘　　要：地下水连通示踪试验总是直接体现地层中强导水带(区)的介质和水动力特征,包括强导水带(区)的结构特征、地下水渗流速度和弥散度等。通过建立地下水连通示踪试验4类20个代表性的地质模型,并用V isualMODFLOW模拟它们的示踪剂运移过程及对模拟结果进行分析,总结出了地下水连通示踪试验的适用条件,给出了示踪剂使用量、观测周期的建议值,获得了地下水连通示踪曲线的一般规律,这对地下水连通示踪试验的实施及示踪成果的解译具有一定的指导意义。Labeled connection test of underground water could generally make known characteristics of medium, water moving force, structure of strong water transmitting belt （zone） in strata as well as seepage velocity and dispersion degree of underground water. The whiter used visual MODFOLW to simulate tracer translation process of 20 typical geologic models of 4 types for labeled connection test of underground water. Analyzing the simulating results, he had summarized suitable conditions of labeled connection test for underground water, obtained general pattern of labeled connection curve of underground water. Then he presents suggestion value for use quantity of tracer as well as observation cycle. This has certain directive function for implement of labeled connection test as well as explanation of its results.
