摘要

针对特高拱坝混凝土运输过程中的信息孤岛化、联动管控难、缆机群安全控制难等问题,该文以白鹤滩水电站工程为例,结合其双平台施工布置特点与多仓同浇的混凝土运输管理难点,提出以缆机为核心的大坝混凝土运输效率联动与缆机群高效安全的分析模型。构建了全面感知、即时分析、反馈预警、动态跟踪的混凝土运输智能管控体系,研发了特高拱坝混凝土运输智能管控平台。该平台在白鹤滩水电站工程中成功应用,实现了混凝土运输效率与安全的数字化管控,有效改善了传统施工中联动分析差、反馈时效性低、过程难以控制等管理难点。研究结果对同类工程大坝混凝土高效安全运输管控具有借鉴意义。

Abstract

Proper concrete transport at super-high arch dams is important for maintaining good concrete properties for dam integrity. This study used the Baihetan project as an example to analyze the problems of isolated information, difficult linkage control and safety control of cable crane groups for concrete transport when building super-high arch dams. The construction was further complicated by a double platform construction layout and the difficulties of concrete transport management with multiple, simultaneous pours. This paper presents a model of the concrete transport linkages and cable crane groups efficiency and safety characteristics with an intelligent management and control system. The system provides real-time analysis, feedback warnings and dynamic tracking in the intelligent management and control platform for the concrete transport. The platform has been successfully applied in the Baihetan project to provide digital control of the concrete transport efficiency and safety to effectively improve the traditional construction management that deals with poor linkage analyses, slow feedback, and poor process control. The research results can be used for similar projects.
