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.
