Dynamic control method for tunnel construction progress based on global comprehensive sensitivity analysis

Abstract

The invention discloses a dynamic control method for a tunnel construction progress based on a global comprehensive sensitivity analysis. The dynamic control method comprises the steps of determining a sensitivity analysis input parameter based on a tunnel construction simulating model, and preprocessing the parameter; performing a multi-factor sensitivity analysis of a tunnel construction period; performing a global sensitivity analysis of the tunnel construction period; performing engineering language transformation on a sensitivity analysis result; and performing real-time dynamic monitoring and controlling on the tunnel construction period. The dynamic control method has functions of realizing dynamic control for the tunnel construction progress, finding unreasonable construction configurations and construction solutions, dynamically adjusting the construction solutions, improving engineering construction precision, performing sensitivity analysis and dynamic control on all parameters which may cause tunnel construction period change, realizing comprehensive understanding for the construction period influence by construction parameters and work procedure duration time, further acquiring more critical parameter in a parameter assembly, and effectively ensuring checking for a construction machinery configuration solution.

Description

Technical field [0001] The invention relates to the technical fields of water conservancy engineering and transportation engineering, and in particular to a method for dynamically controlling tunnel construction progress based on global comprehensive sensitivity analysis. Background technique [0002] With the continuous development of the construction of diversion tunnels, highway tunnels, and railway tunnels, the construction of tunnel projects has received extensive attention. But at the same time, tunnel construction is a huge and complex project. The construction period of the tunnel fluctuates due to the influence of many factors. The fluctuation of the construction period can easily cause the actual construction period to be inconsistent with the planned construction period, which will bring about the arrangement and management of the construction schedule. Inconvenient to come. Using the sensitivity analysis method to control the above problems can achieve the goal of mo...

Problems solved by technology

[0004] Judging from a series of studies and applications at home and abroad, there are not many studies on sensitivity analysis of tunnel construction period, and the research is only single-factor sensitivity analysis or local sensitivity analysis, not all factors that may cause construction period fluctuations Carry out overall comprehensive sensitivity analysis on the impact of construction period, and the research on sensitivity analysis of tunnel construction period is not comprehensive enough, and the guidance effect on actual construction is limited
