There exist shortcomings or restricted conditions in preceding formulae of obtaining the seepage velocity.

地下水渗透流速是一个很重要的水文地质参数,示踪技术可较为准确地估算地下水渗透流速。

Owing to are some questions about the traditional dilution formula and the generalized dilution formula deduced by predecessors,a new dilution formula was derived to calculate seepage velocity with tracer method,based on the condition that there existed vertical flow in the borehole and a reasonable physical model was adopted,considering the seepage velocity as a function of tracer dilution time.

基于传统稀释公式和前人推导的广义稀释公式存在的种种问题,在钻孔中存在垂向流的情况下,在合理的物理模型的基础上,考虑了渗透流速是示踪剂稀释时间的函数,重新推导了示踪方法测流速的稀释公式。
