长大隧道施工组织模糊评价方法及应用

Fuzzy Evaluation Method and Application of Large-long Tunnel Construction Organization

系统分析了长大隧道施工组织的影响因素,建立了包括施工安全、造价、进度和环境四大因素集的隧道施工组织方案评价结构模型;进一步,基于模糊综合评价理论,提出了隧道施工组织多层次综合评价方法,并进行了实例应用。结果表明:依托工程的施工组织方案整体评价等级为“良”,能满足实际施工需要,但仍然存在一定优化空间,需加强工程地质条件、工地生活垃圾、工程运输污染三方面的相关施工组织;指出该隧道施工组织的重中之重是施工安全,影响施工组织设计效果的主要风险因素为施工进度、资源配置优化与控制,为后续施工组织优化提供了依据。

The influencing factors of long tunnel construction organization are analyzed systematically,and the structural model of tunnel construction organization evaluation including construction safety,cost,schedule and environment is established.Furthermore,based on the fuzzy comprehensive evaluation theory,the multi-level comprehensive evaluation method for tunnel construction organization is proposed and applied as an example.The results show that the overall evaluation grade of the construction organization scheme is“good”,which can meet the needs of the actual construction,but there is still some optimization space,and the organization of engineering geological conditions,construction site household garbage and engineering transportation pollution should be strengthened.It is pointed out that the most important thing in the construction organization of this tunnel is the construction safety,and the main risk factors of the tunnel construction organization are construction schedule,resource allocation optimization and control,which provides a basis for the subsequent construction organization optimization.
