重力坝理论断面的设计,一般是由“抗滑稳定”和“应力”两个条件控制的。稳定几乎全部都依靠混凝土重量来维持,所以稳定条件直接影响工程量。如恒仁大头坝应用本文下述公式(1)计算时,将摩擦系数由0.6改为0.7,混凝土量相差15万立米。至于应力条件,对重 The design of gravity dam theory section is generally controlled by two conditions: “anti-skid stability” and “stress”. Almost all rely on the stability of concrete weight to maintain, so the stability of a direct impact on the project volume. For example, Hengren Dadouba uses the formula (1) below to change the friction coefficient from 0.6 to 0.7, and the amount of concrete to be different by 150,000 m. As for the stress conditions, the weight
