基于仿真的长距离引水隧洞施工全过程进度实时控制与可视化分析研究

Whole construction process real-time schedule control and visual analysis of the long distance diversion tunnel based on simulation

长距离引水隧洞常具有埋深大、洞线长、洞径大和工程地质条件极其复杂等特点,各工序工程量大,相互间影响巨大,因此,在实际施工过程中内外环境和约束条件可能发生变化,使原定的施工进度计划与实际施工进程不可避免地产生偏差。如果这种偏差不及时纠正,将会越来越大,以致原计划进度起不到指导实际施工的作用。文章利用计算机仿真技术、控制论思想和虚拟现实技术,提出了基于仿真的长距离引水隧洞施工全过程进度实时控制与可视化分析方法,对施工进度的实时控制提供了可行性研究和科学依据。

Long diversion tunnel is often featured by great embedded depth, long tunnel line, large hole diameter and extremely complicated geologic conditions. The engineering quantity of each process is large, and the influence is enormous; therefore, the internal and external environment and constraint condition are changed in the actual construction, leading to the deviation between formerly construction schedule plan and actual construction schedule plan. If the deviation isn＇t corrected timely, the formerly plan can not guide the actual construction. In this paper, using computer simulation technology, control theory and virtual reality technology, the whole construction process real-time schedule control and visual analysis of the long distance diversion tunnel based on simulation are proposed. The feasibility study and scientific basis is provided for the real-time control of construction schedule.
