基于GA的狭小施工场地平面布置优化研究

GA-Based Optimization of Plane Layout of Narrow Construction Site

摘要: 地铁、城市道路等市政工程施工，大都处于城市闹区，施工场地往往受既有建筑物的制约，且地铁施工场地区域往往狭小拥挤，场内设施的布置往往受到较大的制约，导致施工场地内的施工流通不畅，因此科学合理地对施工场地进行布置显得尤为重要。本文以某市地铁车站一期一阶段场地平面布置为例，结合LEC评价法和施工现场条件构建场地布置数学模型，同时借助遗传算法全局寻优的特点，求解得出最优场地布置方案和场地设施尺寸。

Abstract: Municipal construction projects such as subways and urban roads are mostly located in urban downtown areas. Construction sites are often restricted by existing buildings, and subway con-struction sites are often narrow and crowded. The layout of on-site facilities is often constrained by large restrictions, resulting in construction sites. The construction of the construction is not smooth, so it is particularly important to arrange the construction site scientifically and reasonably. Taking the plane layout of the first phase of a city subway station as an example, this paper combines the LEC evaluation method and the construction site conditions to construct the mathematical model of the site layout. At the same time, the optimal site layout scheme is obtained by means of the global optimization characteristics of the genetic algorithm.
