For jiangpinghe double - curved arch dam, 3 - d elasto - plastic fem is made, in which the point safety factors of the dam - abutments system and the safety margin for coefficients of sliding resistance on 7 potential sliding blocks of the dam before and after the reinforcement of the dam are calculated under the conditions of the normal storage level and the design flood level respectively based on the results from the analysis made with fem
摘要對江坪河雙曲拱壩進行了三維彈塑性有限元分析，利用有限元應力成果分別計算了正常蓄水位、設計洪水位等3種工況下加固前後壩體壩肩系統的點安全系數和7個可能滑動塊體的抗滑富餘系數。 -
Experimental research on crest spillway flood energy dissipation for the double - curvature arch dam
雙曲拱壩壩頂表孔泄洪消能布置試驗研究 -
Hydrology regime and river channel evolution become complex because of double influences of river flow and tide. there is little appropriate method so far. therefore, when the impact us assessed of water project on flood control, the following aspects should be focused on, river evolution and stability of project - sections, design tidal level, flood - tide combination scheme, pre - project and post - project impacts on river channel, water level and flow condition
長江河口段為潮流河段，徑流潮流的雙重作用使得區域水文情勢、河道演變規律錯綜復雜，開展防洪影響評價研究時，河道演變及工程段穩定性分析，設計潮位的分析計算，洪潮組合方案擬定，工程前後對河道及水位流態影響的模擬等均是目前尚無十分成熟的方法，需要進一步研究的課題。
