本文基于渗流的基本定律出发，考虑到现场试验的可行性，以溪洛渡水电站工程为例，提出了一种确定缓倾结构面渗透性参数的现场试验法。文章首先推导出确定缓倾结构面渗透性参数的计算公式，然后利用风钻对典型结构面单独成孔，作简易注水试验，求出结构面的透水性参数。
Based on the basic law of seepage flow and considering the feasibility of field test, a case study of Xiluodu hydropower station is proposed in this paper. In this paper, the formula to determine the permeability parameter of the gentle-dip structure surface is deduced first. Then the typical structure surface is formed into a single hole with a pneumatic drill, and the simple water injection test is performed to obtain the permeability parameter of the structural surface.
