一、前言在传统的坝工设计中,通常是先假定一个坝体形状,然后进行应力和稳定计算,考察是否满足设计规范的要求,如果满足了,就加以采用。从数学上看,这样得到的是一个可行方案,并不一定是一个好的方案。如果设计工作做得更细致一些,也可以多做几个方案,从中挑选一个比较好的方案。这样做的结果,当然比只做一个方案好一些,但所得到的还是在所做的几个可行方案中相对较好的方案,真正的最优方案还可能遗漏掉。另一方面,这种做法所化费的时间也比较长。
I. Preface In the traditional design of dam engineering, the shape of a dam is usually assumed first, and then the stress and stability calculation are carried out to see if it meets the requirements of the design code and if so, it is adopted. Mathematically, what you get in this way is not a good solution. If the design work to do more detail, you can also do more than a few programs, from which to pick a better program. The result of this is certainly better than just one solution, but the result is still a relatively good solution among the several feasible solutions, and the real optimal solution may also be missed. On the other hand, it takes a long time to implement this method.
