摘要
依据达西定律与渗流连续平衡原理，用渗径法对岩石坝基防渗体厚度、深度、降低渗压及渗流量等提出估算方法，并搜集了一些工程实测渗流梯度与渗压系数资料，最后对排水降低渗压作了略述。
According to the Darcy′s law and the flow continuity balance principle ,the author put forth how to evaluate the thickness,depth,depression and seepage quantity of the rocky dam foundation body by percolation path method,gathered the materials of some projects'percolation gradient and percolation pressure coefficient and also discussed the drainage depression .
