三、土方机械的配套和选择以上得出的最优土方调配方案,必须要有优越的施工组织措施保证,才能达到提高经济效益的目的。为了便于与原方案比较,本文在承担该工程公司现有配套机械组合类型(表9)的基础上,采用动态规划的方法来确定最优的配套机械组合类型和投入数量。对土方机械配套和配套数的确定,通常是按施工区域的土方量和运距等作为选择机械经济运行的条件,这种方法虽对各分区域可以得到较好的方案,但对整个工程,对全
Third, the supporting and selection of earth-moving machinery The above-mentioned optimal earth allocation plan must have superior guarantees for construction organization measures in order to achieve the purpose of improving economic efficiency. In order to facilitate the comparison with the original plan, this paper, based on the existing supporting machinery combination type (Table 9) of the engineering company, adopts a dynamic planning method to determine the optimal type of combined machinery and the number of inputs. The determination of the number of earth-moving machinery supporting equipment and supporting equipment is usually based on the amount of earthwork in the construction area and the distance of transportation, etc., as a condition for the selection of mechanical and economical operation. Although this method can obtain better solutions for each sub-area, the overall Full
