摘要
厄瓜多尔CCS水电站项目存在泥沙含量高、地震烈度大、覆盖层埋深大、输水距离长、地质条件复杂、水头高等不利自然条件,基于BIM和信息化设计,采用设计和施工深度融合的动态设计方法,成功解决了在不均匀地基上修建特大规模沉沙池,超深覆盖层上修建大泄量混凝土过水建筑物,国际标准体系下深埋长隧洞设计优化,复杂地质条件下高水头压力管道设计,薄岩壁大跨度地下洞室群支护措施,大容量水轮机和高压发电机配电装置型式选择等一系列关键技术问题,为工程的高质量建设和运行奠定了坚实的基础。
CCS Hydropower Station in Ecuador has adverse physical conditions such as high sedimentconcentration, high-intensity seismic, deep overburden, long-distance of water delivery, complicated engineering geological conditions and high water head. Based on BIM and information design, with dynamic design method of deep integration of design and construction, a series of key technical problems such as extra-large-scale desilting basin built on uneven foundation, large discharge concrete structure on deep overburden, design optimization of deep buried and long tunnel based on international standard system, design of high pressure pipeline in complex geological conditions, supporting measures selection of big span underground cavern groups with thin wall, type selection of high capacity turbine and distribution unit of high voltage generator had been solved successfully.
