摘要
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 principal law of seepage flow, considering the possibility of field test, a new field test method is proposed in this paper for determining the permeability parameters of gently dipping structural face or discontinuity. Firstly, a formula of the permeability parameters of gently dipping is deduced. Secondly, a simple water injection test was carried out in the hole penetrating typical structural faces or discontinuities by pneumatic drilling, then the permeability parameters of them were obtained. As an illustrative example, the Xiluodu Hydropower Station is presented and discussed.
