对高层建筑给水工程,在满足相同技术功能的条件下,可有多种类不同的方案。择优则必须通过技术经济计算比较,而一般的“优劣顺序标度”或“定基比率标度”的比较,尚欠完备。本文按有代表性的五种方案,探求用于定量经济分析计算的公式,最后用表格汇总,展现了明确的经济比较的通式系列。
For high-rise building water supply projects, there may be many different types of solutions under the same technical functions. The best choice must be compared through technical and economic calculations, and the comparison between the general “order of merits and the order” or the “base-ratio ratio” is not yet complete. This article according to the representative five kinds of schemes, seeks the formula used for the quantitative economic analysis calculation, finally summarizes in the form, has demonstrated the explicit economic comparison general formula series.
