示踪试验测定大坝集中渗漏通道渗漏量的研究

The research of determining the seepage value in the concentrative leakage passage of the dam by the tracing experiment

介绍了一种通过示踪试验测定集中渗漏量的流量计算模型,推导了瞬时示踪剂投放下的流量计算公式。结合小浪底大坝30号排水洞中的渗漏来源及渗漏量测试的现场试验,对模型与公式进行了验证。

Introduce a kind of computation model for computing the flow quantity value and derive the calculating formulas by the tracing experiment when the tracers are injected instantly. Then, we verify the model and the formulas by combining the field experiment of researching the different supply sources of leakage water and testing the value of seepage discharge in No. 30 galler at Xiaolangdi dam area.
