寒冷条件下高拱坝施工过程仿真方法研究
Research on simulation method of high arch dam construction process under cold conditions
摘要
Abstract
Construction of many high arch dams is faced with harsh cold weather conditions.However,few previous methods for the simulation directly consider the impact of temperature on construction or the dynamic warehousing based on temperature predictions for utilizing fully the unfreezing temperature period for concrete pouring in the cold season.This paper presents a new method for simulating the construction process of high arch dams under cold conditions based on Informer.First,we establish a temperature prediction model based on Informer to predict future temperature sequences,and apply it to construction analysis.Then,we develop a dynamic partition construction model for constructing a high arch dam under cold conditions,and implement a partition construction simulation strategy applicable in real construction environment,so as to improve the construction simulation and analysis for different temperature conditions.Finally,the Informer model is used to predict temperature in a case study of the Yebatan high arch dam project located in the southwest region,generating an average error of±1.49℃and a daily average error of±1.16 hours of construction time.We compare three different simulation strategies and verify that the dynamic partition strategy is more efficient under cold conditions,demonstrating temperature factor consideration gives improved simulations that are closer to reality than the method of simply reducing efficiency.关键词
