摘要
小湾拱坝高达294.5m,总水推力为176520kN。拱坝应力水平高,最大主压应力按10MPa控制。工程位于强地震区,拱坝抗震设防要求高。通过可行性研究、初步设计以及国家"九五"科技攻关等一系列研究,逐步解决了小湾拱坝体形优化、坝踵防裂防渗、抗震、泄洪消能、坝基基础处理和坝肩抗力体地质缺陷处理等关键技术。
The maximum height of Xiaowan arch dam is 294.5m, and the total hydraulic thrust load undertaken by the dam is amount to 176 520kN. The dam stress level is high, and the maximum design compressive stress is controlled to be less than 10MPa. The dam is located in strong earthquake zone, so its seismic fortification design must meet related requirements. After many studies and researches, some key technologies, such as the shape optimization of arch dam, crack and seepage control at dam heel, the seismic fortification measures, the flood discharging and energy dissipation measures, dam foundation treatment and the abutment foundation treatment, have been solved progressively.
