土石坝设计在过去十到二十年间,经历了许多变革,产生了一些新方法,也淘汰了一些旧方法。导致土石坝设计发生变革的原因,主要是为了要降低工程造价,而在某些情况下也是为了要提高其安全度。土石坝设计方法的改变是一个渐变过程,记述这些变革的文献资料每每落后于现 In the past ten to twenty years, the design of earth-rock dams has undergone many changes, resulting in some new methods and the elimination of some old methods. The main reasons for the changes in the earth-rock dam design are to reduce the construction cost and, in some cases, to improve its safety. Changes in the design method for earth-rock dams are a gradual process, and the literature describing these changes often lags behind
