高速公路施工工序优化设计

Optimization Design of Highway Construction Process

为了提高效率、缩短工期、减少施工对交通的影响,会存在多个施工区同时施工的情况,而实际的施工过程会出现工序不紧凑、进度调整困难、工期拖延等问题,因此文章选择从实际出发,结合贪婪思想,找到路段上能够同时施工的最大施工区数量,在施工区通行能力、路网效率等约束下,找到使施工时间最短的工期安排,提出施工工期的优化算法。

In order to improve the efficiency, shorten the construction period and reduce the impact of construction on traffic, there will be multiple construction zones at the same time. However, in the actual construction process, there will be some prob-lems, such as incomplete working procedures, difficulty in adjusting progress, delay of construction period, etc. Therefore, this chapter chooses to proceed from reality, combined with greedy ideas, to find the maximum number of construction zones that can be constructed at the same time in the construction zone. Under the constraints of traffic capacity and road network efficiency, the shortest construction period is found, and the optimization algorithm of construction period is put forward.
