光滑裂隙水流模型实验及其机理初探

The model test of the folw in smooth fracture and the study of its mecchanism

本文通过裂隙水室内模型实验研究，将理论值与实验作了对比分析，阐述了立方定律的适用范围，同时，对微裂隙水流运动亦进行了初步研究，在实验的基础上，通过机理分析和实验研究的总结，得出了微裂隙水运动不完全属于牛顿流体运动的初步结论。在紊流实验的基础上提出了一个半经验公式，经比较，与实测结果较为一致。

A model test and mechanism study of the flow in smooth fracture was conducted and the test data were compared with the theoretical results. It is concluded that the cubic law is valid only a limited range. The now in micro-fracture is also modeled. The analysis of experimental data shows that the motion of the flow in micro-fracture doesn't fully obey the law of Newton's fluid. A semi-experimental formula is proposed to calculate the turbulent flow in the fractures and the results are well agreed with experimental data.
