| 摘 要： | 本文采用有限单元法,对加固重力坝基础缓倾角软弱结构面抗滑硐塞系统的破坏机理进行了初步分析。认识到抗滑硐塞的受力状态和破坏机理是复杂的,最终破坏形式与硐塞布置位置、高宽比、以及硐塞混凝土和周围岩体的物理力学性质等有关。以此为依据,对抗滑硐塞系统的破坏形式进行了分类,并对目前采用的抗滑硐塞设计方法进行了分析。

| Abstract: | In this paper, through mathematically imitating the slightly inclined weak layer consolidated with shear keys in the gravity dam foundation, the failure mechanism of shear keys is studied. It is recognized that the force-receiring condition and the failure mechanism of shear keys are complicated. The final failure form is concerned to their location, ratio of height with width, the physical mechanical properies of the concrete and surrounding rock masses. At the end, the failure forms of shear keys system are classified and the present method of designing shear keys is discussed. |
