观音岩水库碾压混凝土双曲拱坝优化设计研究

Optimal Design of Rolled Compaction Concrete Double - Curved Arch - dam of Guanyinyan Reservoir

观音岩水库大坝是一座采用碾压混凝土技术的变厚双曲抛物线拱坝,最大坝高109 m,坝基地质条件较复杂,需要在可研阶段对大坝方案进行深入研究。借鉴国内外拱坝设计和建设施工经验,以规范为基础,佐以ADASO等电算程序,对观音岩水库大坝体形、坝体结构、大坝应力、坝体温控、基础处理等进行详细论证分析。观音岩水库拱坝优化调整方案,不仅能够满足技术规范要求,同时其技术经济效益较为显著,其设计经验可供同类工程设计人员优化设计参考、借鉴。

Guanyinyan reservoir dam is rolled compaction concrete double curved thicken and cur vature arch dam with 109m high, and the geologic condition of dam foundation is complicated, which need to do the deep research during the study design stage. Referring to the abroad and domes tic arch dam design and construction experience, using the criterions as the design fundament, com bining ADASO design procedure, the researches about the arch dam architecture shape, dam struc ture, dam stress, dam temperature control and foundation treatment of Guanyinyan reservoir dam pro ject are carried out. The arch dam adjustment optimal design scheme of Guanyinyan reservoir not only can meet the requirements of the technical criterions standards, at the same time the technical and economic benefit is obvious, and the design experience can as the optimal design reference for the similar engineering.
