石坎梯田的优化设计

通过对石坎梯田断面要素和工程量的分析,以田坎高度和田坎侧坡坡率作为设计变量,以每公顷梯田的造价为目标函数,提出了石坎梯田的通用优化设计数学模型,并进行了实际优化计算。优化设计结果和常用的石坎梯田规格相比,优化设计的石坎梯田要比常用规格安全经济得多。

Optimum Design of Terraces with Stone Banks

This paper, based on the analyses of the essential factors constituting the cross-section of terraces with stone banks and the amount of engineering works, put forward an universal mathe-matic model for the design of this kind of terraces, using height and side-slope of stone bank as its design variables and cost of per hactare terrace as its objective function. Real optimum calculation is also made, the results show that the optimal designed terraces are much more safe and economic compared with that designed according to normal specifications.
