不良地质条件下长距离引水隧洞施工全过程进度仿真与实时控制研究

长距离引水隧洞常具有大埋深、长洞线、大洞径、高地应力水平、极其复杂的工程地质条件等特点 。大埋深和高地应力引起的岩爆及高涌水等地质问题对施工进度计划安排和控制影响非常大，尤其是对不良地质段的施工进度控制是整个工程能否按时完工的重中之重。结合循环网络的系统仿真与网络进度计划分析技术，提出了针对不良地质条件下长距离引水隧洞施工全过程进度仿真与实时控制方法。该方法可以对实时进度施工方案的变更和选择提供可行性研究和科学依据，为准确、迅速进行实时进度控制提供技术支持，增强实时施工进度的可控性。

Simulation and real-time control of whole construction progress of long-distance diversion tunnels under unfavorable geological conditions

The long-distance diversion tunnel is often characterized by great embedded depth,large hole diameter,long tunnel line,high ground stress and extremely complicated geologic conditions.Geologic issues like rock burst and high water gushing caused by big embedded depth and high ground stress have great influences on the construction schedule arrangement and control,especially the construction progress control for bad geological section,which is a key to the periodical completion of the whole project.Combined with the circular network system simulation and network project analysis technique,a simulation and real-time control method for the whole construction progress of long distance diversion tunnels under unfavorable geological conditions is presented.This method can provide feasible study and scientific basis for change and selection of real-time progress of construction scheme so as to realize accurate,fast real-time schedule control and to enhance the construction progress of real-time control.
