摘要
构皮滩拱坝坝高232.5m,坝基地质条件复杂,坝身孔口多、规模大,拱坝规模和技术难度均超出现行拱坝设计规范的控制。借鉴国内外高拱坝设计经验和最新研究成果,采用多种分析方法和模型试验,结合工程类比,对构皮滩拱坝体形、应力、坝肩稳定、抗震和基础处理等进行了研究分析,并结合工程实际施工情况,对大坝进行适当优化调整,使拱坝设计最终达到安全可靠,技术可行,经济合理。
Goupitan arch dam is 232.5 m high with multiple large orifices, the geologic condition of dam foundation is complicated. The arch dam scale and techni cal difficulty are beyond the arch dam design standard currently in effect. Using the abroad and domestic arch dam design experience and most up-to-date scienti fic research achievement for reference, adopting various analysis methods and model tests and comparing with the similar project, the researches on the arch dam configuration, stress, dam abutment stability, anti-quake and foundation treatment of Goup itan project were carried out, and in the light of concrete condition of the project, the dam is optimized properly, realizing the project design objectives of safety and reliability, technical feasibility, economic rationality.
