摘要

300 m级特高拱坝工程大多水文地质条件复杂、工程规模大、工期紧张、质量控制严,其施工进度受诸多内外部复杂因素的共同作用和制约。针对白鹤滩工程双缆机平台及双供料平台布置、多标段施工、采用自升模板等新工艺、大风天气等特点,研究了多维约束条件对高拱坝施工进度的耦合作用机制,基于智慧大坝系统的智能感知信息并利用多维耦合的仿真分析技术,分析了白鹤滩高拱坝的施工进度控制关键因素和关键路径,为白鹤滩大坝和类似工程施工精细化管控提供了有效的支撑手段和决策依据。
        300 m-high arch dams are always characterized by complex geological conditions,large engineering scale,tight construction duration and strict quality control,so its construction progress is affected by many internal and external constraints.In view of the features of double cable platform and double feeding platform,multi-contracting construction,new construction technologies such as self-lifting formwork and windy weather in the construction of Baihetan Hydropower Station,the coupling mechanism of multiple constraints on the construction progress of high arch dam is studied. In combination with the intelligent sensing information of smart dam system and multi-dimensional coupled simulation analysis technology,the key factors and the critical path of Baihetan Dam construction are analyzed,which provides an effective supporting means and decision-making basis for the fine control of construction of Bahihetan Dam and similar projects.
