| 摘 要： | 介绍了以四角棱柱体土方公式为计算模型的试算法确定大型场地平整最优设计标高近似解的方法.该试算法通过输入一组符合生产工艺要求的设计标高区间值,计算出相应的场平工程总挖方量与总填方量之差以及总挖方量与总填方量之和.经过数值比较后选择使两者均较小的设计标高方案进行经济分析,确定造价最低的标高方案为最优设计标高近似解.

| Abstract: | In this paper,the approximation calculation method based on calculation model of earthwork formula of tetragonal prism is described. The optimization design elevation in large earthwork can be determined by this method. Through introducing a set of different design elevations, the difference between and sum of the total excavation and the total fill can be calculated. An economical analysis is carried out on the design elevation chosen with little value for both cases by numerical values comparison. The elevation with the lowest cost is taken as the optimal design elevation. |
