地下厂房洞室群施工是一项影响因素众多、关系复杂的系统工程,传统的施工组织与管理手段已经不能满足大型地下洞室群施工组织与管理的需要,最终会影响工程建设目标的实现。如果能够结合现代施工组织理论及计算机技术对工程的施工方案进行优化,提高施工管理水平与效率,所产生的经济效益和社会效益是相当可观的。对某水电站工程地下厂房洞室群施工进行系统地分析,以地下厂房洞室群施工为模拟对象,集网络计划技术、循环仿真随机网络技术、系统仿真技术于一体,利用工序模型和活动模型2个层次建模技术,对该工程地下厂房洞室群施工过程进行仿真,为该工程优化施工机械设备,合理安排施工进度,提高施工管理工作效率提供参考。
The construction of underground powerhouse caverns is a systematic project with many influencing factors and complex relations. The traditional construction organization and management methods can not meet the needs of construction and management of large underground caverns and will ultimately affect the realization of engineering construction goals. If we can combine the theory of modern construction organization and computer technology to optimize the construction plan of the project and improve the construction management level and efficiency, the economic and social benefits will be considerable. This paper systematically analyzes the construction of caverns in underground powerhouse of a hydropower station project, and takes the construction of underground powerhouse caverns as simulation object. It integrates the network planning technology, the random simulation network technology and the system simulation technology, and uses the process model and activity model 2 Level modeling technology to simulate the construction process of the caverns in the underground powerhouse of the project and provide reference for optimizing the construction machinery and equipment, rationally arranging the construction progress and improving the construction management efficiency of the project.
