摘要
在对高心墙堆石坝坝面碾压系统进行全面分析的基础上,提出了以填筑单元为仿真单位的碾压施工仿真理论,建立了能够反映碾压过程中不确定因素的精细化仿真模型,保证仿真贴近实际施工。研究成果在糯扎渡心墙堆石坝工程的填筑单元中得到了应用,验证了方法的可靠性,对于大坝现场碾压施工具有指导意义,为工程进度控制和管理提供了技术支持。
Based on the overall analysis of roller compaction system of high core rock-fill dam, the theory of construction simulation for roller compaction is put forward and the simulation model is set up which can actually reflect the uncertainties of the rock-fill dam roller compaction to ensure the simulation to be more close to the actual construction. This study achievement has been applied to the filling unit construction process of the Nuozhadu high core rock-fill dam to verify the reliability of the simulation model, which gives important guidance to the project. Meanwhile , the technical support is applied for the schedule control and management.
