线性工程项目进度计划LSM以线性工程整体作为单独工作面进行分析,通过简单的线段组成图表,展现工作时间、工作顺序和搭接顺序之间的关系,该方法可视化程度高,并能描述线性工程的空间位置和工作效率,在线性工程计划中得到了广泛应用.但是,在实际线性工程施工中,施工距离较长,存在多个同期工作面,LSM计划图出现多个工作面进度的叠加,整体进度计划出现紊乱,无法进行全路段优化.根据实际线性工程项目的特点,提出了多工作面条件下的分类判断,建立多工作面线性计划模型,提出了一种针对工序间隔时间的优化算法,并根据优化算法进行实例分析,改进了线性工程项目进度计划.%Linear project schedule LSM analyzed linear engineering overall as a separate working face through a simple line forming chart,Presented work time, work sequence and the relationship between the overlapping sequence. Besides high degree of visualization, the method can describe the spatial position of the linear engineering and work efficiency, and it has been widely applied in the linear project. However, in actual linear engineering construction, construction distance is longer, and in the same period there are multiple working face. LSM plan appear many face the progress of the overlay, the overall schedule turbulence, to the whole road section optimization. According to the characteristics of the actual linear engineering projects, this paper puts forward the working face under the condition of more classification judgment, and set up multiple linear planning model of mining face. This paper proposes a optimization algorithm for process time interval, and according to the optimization algorithm is analyzed, improved linear project schedule.
