摘要
本文所提出的经验公式,采用限制面板蓄水引起的稳定挠度及其要求的堆石压缩模量,限制面板压应力,以达到防止垂直缝面板发生挤压破坏的目的。本文还利用这些公式,探讨了使用石灰岩坝料建造300m高面板坝的可能性。
The derived empirical formulas in this paper, can be used for estimating stable face slab deflection induced by reservoir water load for giving dam height and measured rockfill compressive modulus, and a critical rockfill compressive modulus and deflection are required to avoid face slab crushing along vertical joints for giving dam height and valley shape. A required porosity vs dam height empirical formula has been established for lime rockfill dam.
