溪洛渡水电站右岸地下厂房岩壁梁岩台开挖质量管理 总被引:3,自引:0,他引:3
岩壁梁岩台是地下厂房系统中受力最大的结构,岩台开挖质量直接影响到桥机运行安全.溪洛渡右岸地下厂房岩壁梁岩台宽1.75 m,斜面长3.13 m,堪称世界之最.溪洛渡右岸地下厂房岩台开挖在总结多个地下厂房岩台开挖成功经验的基础上,采取一系列行之有效的质量管理措施,最终实现了"典范岩台"的开挖质量目标. 相似文献

介绍SIMHYD降水径流模型的结构及计算原理,利用该模型模拟了丹江口以上汉江上游流域的月流量过程,并采用区间分析方法分析SIMHYD模型参数的敏感性。结果表明:SIMHYD模型可以较好地模拟该流域的月流量过程;根据参数敏感性大小可将SIMHYD模型参数归为3类:第1类为敏感参数,如SMSC和SUB;第2类为较敏感参数,如CRAK和K;第3类为非敏感参数,如INSC,COEFF和SQ。 相似文献

Analysis of causes of erosion-corrosion wear of the metal of internal surfaces of watered regions of tubes of heat-exchange devices 总被引:1,自引:0,他引:1
I. I. Belyakov V. I. Breus 《Power Technology and Engineering (formerly Hydrotechnical Construction)》2006,40(1):44-49
Causes of the appearance of erosion-corrosion wear (ECW) on inlet regions of tubes of heat-exchange devices are considered.
Experimental data are used for determining the mechanism of the ECW process and suggesting measures for its prevention.

Conclusion The method examined above of predicting the reworking of banks of the LR of a PSS similar to the LR of the Dnestr PSS does not claim completeness and rigorousness of the solution and, naturally, should be refined by data of subsequent onsite observations and investigations, which will make it possible to perfect both the calculation method itself and its theoretical basis.Translated fromGidrotekhnicheskoe Stroitel'stvo, No. 2, pp. 16–21, February, 1989. 相似文献

桂林城市化水文效应分析 总被引:1,自引:0,他引:1
城市空间在流域内的范围很小,但城市化对降雨径流的形成影响很大,城市化对水环境改变也十分显著,造成水资源污染和供需矛盾日益突出。城市水文水资源研究对城市规划与建设有着十分重要的意义。 相似文献
