In recent decades, many public buildings, located in seismic-prone residential areas, had to grapple with abnormal loads against which the structures were unguarded. In this piece of research, an ordinary three dimensional reinforced concrete building is selected as case study. The building is located in an earthquake-prone region; however, it is designed according to seismic building codes. Yet, it is not shielded against abnormal loads, such as blasts. It is assumed that the building suffers a blast load, due to mechanical/thermal installation failure during or after intense seismic oscillations. These two critical incidents are regarded codependent and compatible. So the researchers developed scenarios and tried to assess different probabilities for each scenario and carried out an analysis to ensure if progressive collapse had set in or not. In the first step, two analysis models were used for each scenario; a non-linear dynamic time history analysis and a blast local dynamic analysis. In the second step, having the structural destructions of the first step in view, a pushdown analysis was carried out to determine the severity of progressive collapse and assess building robustness. Finally, the annual probability of structural collapse under simultaneous earthquake and blast loads was estimated and offered.

应用新安江模型进行水文模拟时,由于模型本身的不足及参数多、信息量少等原因,会出现率定的最优参数组不唯一、不稳定等问题。考虑到以往的参数优选,都只得出一个参数组,不能反映出其不确定性状况。提出应用基于马尔可夫链蒙特卡罗(MCMC)理论的SCEM-UA算法,通过双牌流域以1 h为时段间隔的36场典型洪水数据对新安江模型参数进行优选和不确定性评估。结果表明,该算法能很好地推出新安江模型参数的后验概率分布;率定和检验结果分析也表明,应用SCEM-UA算法对新安江模型进行优选和不确定评估是有效和可行的。

随着海水养殖规模的增大,超负荷养殖使得养殖水环境遭到严重破坏,病害加剧,危及养殖产业的可持续发展。亟待加强养殖容量研究,建立科学的适应性管理对策。本文综述了国内外有关海水网箱、贝类、藻类等养殖容量研究进展、存在的问题。指出了容量评估的关键技术,主要包括:生态容量评估的指标体系、养殖生物个体生长数值模型、水动力过程与生态模型的耦合。分析了养殖容量研究在指导养殖密度调整、优化养殖布局、拓展养殖空间以及构建新型养殖模式中的作用。对于未来开展养殖容量研究提出了三点建议:建立养殖水域的容量评估制度、设立近海养殖结构与养殖容量评估的长期监测实验站、设立养殖容量研究和布局与结构调整专项,以建立生态系统水平的养殖管理策略。
