自振法试验及对比应用研究

Self-Oscillation Method and the Contrast Experiment

基于含水层中水体振荡时的阻尼特性和含水层的渗透特性两者具有等效性的特点,所提出的自振法试验,是一种全新的水文地质快速勘探技术。该方法是建立在科学理论基础上的,与常规抽水试验相比,试验设备轻巧,试验周期较短,自动化程度高,试验成本较低。通过对比试验,该方法所测得渗透系数与常规抽水试验渗透系数数值有很好的相关性。

Based on the equivalence of the water body oscillation damping characteristic and seepage characteristic, self-oscillation method is brand-new and fast exploration technology of hydrological geology. Comparing with conventional pumping test, this one is lightweight with short period. And this equipment can be run with high automation and low cost. Through the contrasttest, the seepage coefficient from this method has the very good relevance to the conventional pumping test.
