摘要
两岔河水库是贵州省兴修的第１座碾压砂砾石混凝土面板堆石坝。本文对两岔河砂砾石的物理力学性能进行分析，认为砂砾石的压实性好、抗剪强度高、压缩性低，不论是颗粒级配还是工程性质均可满足坝体各分区的要求；对坝体分区、设计技术指标、施工参数以及１年来的填筑施工、斜坡碾压、砂浆固坡、质量控制等方面的具体作法，进行了全面的介绍。
The Liangcha dam is the first rockfill one with a concrete face dam in Guizhou province. This paper gives mechanical testing results of sand-gravel materials in the Liangcha river that show good compaction, high shear strength and low compression behavior. The materials in both panical grades and engineering, behaviors can meet the requirements of different parts of the dam body. And it also discribes a stlbzone in the dam body, design specification, construCtion parameters as well as embankment, slope compaction, sound slope with cement mortar and quality control.
