混凝土硐塞加固重力坝基缓倾角结构面等K设计方法研究

Study on the Equal K Design Method for the Gentle Sloping Fissure Strengthened by Shear Keys at Gravity Dam Foundations

在过去研究工作的基础上，提出了估算抗滑硐塞总宽度和等安全系数设计各硐塞宽度的公式，以及抗滑硐塞等Ｋ设计的方法和步骤，并进行了实例分析．结果说明提出的方法是可行的，可经济、安全。

Based on the acquired research results,the formulae used to estimate the total width of shear keys and to design the width of every key are presented.The equal K design method and procedure for keys against sliding are given.The example analyzed in this paper shows that this method is practicable and that the economic, safe and equal K design of shear keys can be conducted.
