重力坝溢流坝段自重荷载计算

重力坝是一种主要依靠自重来维持稳定的坝型，自重荷载计算的精度对重力坝设计质量有至关重要的影响。而重力坝的溢流坝段剖面由多段曲线组成，实际工作中往往以折线来代替曲线采用近似计算，既影响了工程设计的精度，又不易编制成程序利用计算机运算。本文推导了一套重力坝溢流坝段的自重荷载计算公式，用于混凝土坝和浆砌石坝等实体重力坝。用此套公式可编制程序，利用计算机进行坝体剖面优化设计，提高工程设计成果的精度，提高工作效率。

Dead Weight Loading Calculation of Overflow Section of Gravity Dam

Gravity darm is the dam whose stability mostly depends on its dead weight and the ac-curacy of dead weight loading calculation has a vital influence upon the quality of gravity dam de-signing. Hhaever,the overflow section profile of gravity dam is composed of several curves, so approximately operations are often used in pratice by repacing curves with fod lines, which notonly affects the accuracy of project designing but also has diffculty in programming and calculat-ing on the computer. This aticle deduas a set of formlas for dead weight boing calculation of overflow secion of gravity dam that can be adopted in solid gravity dams such as concrete dams and grouted rubble dams. The Set of formlas can be ed to program, thereby using computers to optimize dams profile designs, which improves both the accuracy of projects designing and workefficiency.
