堤防工程土石方调配优化模型与应用

Optimal model of earth-stone work allocation in embankment engineering construction and its application

通过对堤防工程土石方施工中土石方调运系统的分析,找到了该系统的问题所在与求解方法,建立了堤防工程土石方优化调配的坐标体系、最优化调配模型.坐标体系以堤防中心线为坐标轴,堤防的一端为原点,堤防上任意一点的坐标为该点的桩号减去原点的桩号.模型考虑了开挖、填筑、采土、弃土等要素,产生理论上的最优土石方调配方案,且模型结构简单,计算方便.

According to the analysis of earth-stone work allocation problem in the construction of embankment engineering, the characteristic and objective of the system are summarized. The coordinate system and the optimal model for the problem are established. The coordinate system regards one endpoint of the embankment as the origin and the central line of embankment as coordinate axis. The coordinate value of any point of embankment is the difference between the stake number of this point and the origin. Works of excavating, filling, discarding, and mining of earth and rock are take into account in the model. The model can produce the optimal allocation scheme; and it＇s simple and easy-use.
