汤河水库溢洪道存在的问题及解决方案

汤河水库溢洪道目前存在诸多问题:原溢洪道工程布置不完全,河道冲刷严重,岸坡冲、淘日趋严重,下游村民生命财产受到威胁等。通过对问题产生的原因进行分析探讨,提出了对水库溢洪道改建的建议。并给出了3个推荐方案,作了成果分析,优选出了最佳方案。     

大伙房水库主溢洪道加固原因分析及方案确定

大伙房水库主溢洪道加固是大伙房水库除险加固工程中的一个重要项目之一。着重从堰上水面线和水工结构两大方面对主溢洪道加固的原因进行了详细的分析,并且介绍了主溢洪道控制段、泄槽底板和泄槽边墙的加固方案。加固方案的确定有效地缩短了工期,节省资金,加固后主溢洪道发挥了显著的防洪效益。该加固方案对以后此类型溢洪道的加固具有一定的参考价值。     

大伙房水库主溢洪道三维流场数值模拟

采用RNGk-ε双方程模型模拟湍流,利用流体体积分数法(VOF)确定自由水面线,笛卡尔自适应网格与部分面积体积障碍模拟法(FAVOR)处理复杂的几何边界,成功地对大伙房水库主溢洪道流场进行了三维紊流数值模拟,得到了自由水面、溢洪道堰面压力、断面流速大小、分布和三维流场的分布规律,结果分析表明数值模拟与物理实验结果吻合较好。     

西泉眼水库枢纽布置优化

优化西泉眼水库枢纽布置及建筑物形式，在施工图阶段，根据运用要求，结合具体地形，地质等条件，使枢纽布置做到紧凑合协调，建筑物形式选择合理，流量系数大幅度提高；消能效果理想，减少开挖，便于施工；消除了运用中隐患，工程安全性明显提高。     

Dam safety management for sustainable farming businesses and catchments

In most countries, owner responsibility exists under Common Law to manage and maintain dams according to current standards. However, farm dam safety in Australia is being flouted and the sustainability of farming businesses compromised because of the potential and severe consequences of dam failure. This paper explores management and policy issues associated with safety of farm dam water storage through a comparison of developments in two Australian states against international benchmarks. Historical review and a longitudinal study over a 12-year period provides the basis for case analysis and demonstrates the application of the benchmarked model policy selection guidelines. Research results show South Australia is lagging international best practice in a number of ways whilst Tasmania provides leadership. The contribution of this paper is a regulatory mix analysis approach, incorporating a cost-effective spillway safety engineering/accounting tool, developed and demonstrated through Australian case studies, that can be applied by any jurisdiction wanting to check and/or improve its farm dam safety management and provide a clearer analysis of the social and environmental costs and threats associated with on-farm dam safety issues.
