瀑布沟大坝工程雨季填筑施工技术

The Rainy Season Filling Construction Technology of the Main Dam Project of Pubugou Hydroelectric Plant

瀑布沟大坝主体工程具有填筑量大、工期紧、强度高、填筑技术要求高、质量标准严的特点。砾石土心墙料的填筑与生产则更是重中之重,是制约大坝填筑的关键。而砾石土填筑受雨季施工影响较大,因此,探索大坝工程在雨季填筑施工措施,对砾石土料高效快速填筑打下很好的基础。

Pubugou dam the main project has a filling volume, tight, high strength, filling technology requires high quality standards and strict. Filling and production of the gravelly soil of the core material is even more the most important constraints rockfill dam critical. Gravel soil filling the rainy season, con- struction impacts, so filling construction measures to explore the dam project in the rainy season, and has laid a good foundation for fast and efficient filling of the gravelly soil.
