Self-adaptive simulation analysis method for construction progress of high arch dam

Abstract

The invention discloses a self-adaptive simulation method for a construction progress of a high arch dam. Self-adaptive updating of a construction progress simulation system for the high arch dam is realized by establishing a self-adaptive simulation mathematical model for the construction progress of the high arch dam, taking a field real-time construction state as the basis, and real-time updating of a simulation initial condition, simulation logic and a simulation construction parameter as the means, wherein real-time updating of the simulation initial condition is realized based on the practical construction progress of an engineering; according to a construction parameter acquired in a field in real time, real-time updating of the simulation construction parameter is realized by adopting a corrected Bayes updating method; and, in a simulation calculation process, on the basis of the real-time construction progress or the simulation calculation speed, real-time updating of dam block selection logic is carried out by adopting an entropy weight method. On the basis of the method, self-adaptive updating of the construction progress simulation model is realized; real-time tracking and analyzing of the construction progress simulation model on the field construction are ensured; and a reasonable construction scheme can be established according to the simulation analysis calculation.

Description

technical field [0001] The invention relates to the field of high arch dam construction progress simulation, in particular, relates to a high arch dam construction progress self-adaptive simulation analysis method; involves high arch dam construction progress information collection, construction progress simulation model self-adaptive update and construction progress simulation Calculation method. Background technique [0002] my country's exploitable hydropower resources and current construction scale rank among the top in the world. At present, most hydropower resources are developed in the western alpine and canyon regions. Arch dams are one of the most widely used dam types in high dam construction in this region. High arch dams are often located in high mountains and valleys with geological conditions and steep terrain, and the construction time span is large, the amount of concrete pouring is large, the construction conditions are complex, and the construction layout i...

Problems solved by technology

[0006] (1) The construction process of high arch dams lasts for a long time, and the actual construction parameters on site will continue to change with the progress of the construction progress. The current research has not considered that the construction parameters in the simulation of high arch dams are updated with the progress of the simulation progress. characteristics, leading to a large deviation between the simulation calculation results and the actual construction progress;

[0007] (2) During the simulation calculation process, the logic of dam block selection is basically fixed, and the current research has not considered the real-time update of the dam block selection logic according to the actual construction progress, which reduces the persuasiveness of the dam block selection logic
