潍坊抽水蓄能电站上水库大坝施工仿真研究

Construction Simulation Study on the Upper Reservoir Dam of Pumped Storage Power Station in Weifang

摘要:

潍坊抽水蓄能电站上水库堆石坝为沥青混凝土面板堆石坝,坝体开挖填筑工程量大,且全部利用库盆开挖料筑坝,开挖、填筑高差大,作业面有限,强度高,需研究开挖填筑程序及施工道路布置的合理性,确保在合理工期内完成上大坝开挖填筑施工。因此,在已有堆石坝施工仿真模型研究的基础上,综合考虑上坝道路布置、坝面作业施工组织、机械资源配置、坝体填筑高差、弃渣场布置与沥青摊铺施工等复杂约束条件,构建全过程的潍坊抽水蓄能电站上水库大坝施工过程仿真模型,实现施工过程仿真分析,为上库库盆开挖与填筑施工提供参考。

Abstract:

The rockfill dam with asphalt concrete face for the upper reservoir of Weifang Pumped Storage Power Station features large quantities of dam excavation and filling works. All filling materials are sourced from reservoir basin excavation spoils, with a large elevation difference between excavation and filling areas, limited working surface and intensive construction intensity. It is necessary to verify the rationality of excavation-filling procedures and construction road layout to ensure the completion of dam excavation and filling within the scheduled construction period. Based on existing research on construction simulation models for rockfill dams, this study establishes a full-process construction simulation model for the upper reservoir dam of the Station. The model comprehensively considers multiple constraints including access road layout, dam surface construction organization, mechanical equipment allocation, elevation difference of dam filling, spoil yard arrangement and asphalt paving construction, and realizes the simulation analysis of the whole construction process, offer a reference for similar construction projects.
