摘　　要：为实现高海拔地区特高心墙堆石坝心墙填筑进度的仿真模拟,综合考虑心墙填筑过程中仓面施工料源供给、高海拔区气象特征和仓面施工参数对施工进度的影响,建立了气象预测和料源供给强度、施工机械配置等仿真参数自适应调整的高海拔地区特高心墙堆石坝心墙填筑进度仿真模型。将该仿真模型应用于某特高心墙堆石坝心墙填筑进度管控,结果表明:仿真结果与实际施工进度偏差为2.17%,比传统仿真方法仿真结果更符合施工实际情况,可用于现场施工进度仿真分析。In order to realize the simulation of the filling progress of core walls in ultra-high core rockfill dams in high-altitude area,the influences of material supply for warehouse surface construction,meteorological characteristics of high-altitude area,and construction parameters of warehouse surface on the construction progress of core wall filling were comprehensively considered.A simulation model of the core wall filling progress of ultra-high core rockfill dams in high-altitude area with self-adaptive adjustment of simulation parameters of meteorological forecast,material supply intensity,and construction machinery configuration,etc.was established.The simulation model was applied to filling progress control of the core wall of an ultra-high core rockfill dam.The results show that the deviation between simulation results and the actual construction progress is 2.17%,which is more in line with the actual construction situation than those of the traditional simulation method,and the model can be used for on-site simulation analysis of construction progress.
