根据铁路施工组织设计指南,对各类主要工程及控制工程施工工期进行分析计算,提出了合理的施工工期。同时根据各类工程确定的施工工期范围,制定出了几个合理的工期方案,并分析各个方案的优缺点,最终选出经济比选较优且施工难度较小的工期方案作为项目的建设工期安排。 According to the railway construction organization design guideline, the construction period of all kinds of major projects and control projects is analyzed and calculated, and a reasonable construction period is proposed. At the same time, according to the range of construction period determined by various types of projects, several reasonable duration plans have been worked out, and the advantages and disadvantages of various plans have been analyzed. Finally, the construction schedule with better economic performance and less difficulty in construction has been selected as the construction period of the project arrangement.
