前言混凝土是拱坝的主要材料。为充分利用混凝土的强度,设计拱坝时必须搞清由库水引起坝体应力的大小;与此同时,为选择拱坝的最佳形状,根据坝址的地质、地形条件进行多次试算很有必要。拱坝应力分析中,既简便、花钱又少的方法就是广泛使用的载荷分配法。但载荷分配法中包含有不少假定,所以其解析精度必然不会高。因此拱坝应力分析时,通常利
Preface Concrete is the main material for arch dams. In order to make full use of the strength of the concrete, when designing arch dams, it is necessary to ascertain the size of the dam stress caused by the reservoir water; at the same time, in order to select the best shape of the arch dam, multiple trials are performed according to the geologic and topographic conditions of the dam site. necessary. In the stress analysis of arch dams, the method that is both simple and costless is the widely used load distribution method. However, the load distribution method contains many assumptions, so its resolution must not be high. Therefore, when arch dam stress analysis, usually
