某医院总建筑面积约19.8万m.(2),门诊大厅采用钢制树形柱+单层铝合金屋盖结构体系,采用Z字形单层铝合金屋盖结构,东西向长度为104.963 m.南北向最宽处为47.427 m.为了营造轻松的视觉氛围,在南北主楼中间的位置采用铝合金门诊大厅“飘带”,形成一个以流畅曲面覆盖的公共大厅,作为患者踏入医院的起始点和主要交通空间。用流畅的曲面“飘带”作为院区的视觉中心,体现轻盈、现代、时尚的理念,空间通透明亮,极具现代感。虽然大跨度铝合金结构应用越来越多,但目前我国暂无Z字形大跨度钢铝组合屋盖结构安装案例可参考,因此研究轻材质大跨度铝合金屋盖结构综合施工技术具有重要的意义。

气候变化和人类活动等因素使洪水序列的一致性遭到破坏,因此推求非一致性条件下的设计洪水具有重要的理论和实践价值。以云南省盘龙河龙潭寨水文站为例,采用实测、模拟和预测的降水和洪水数据,基于GAm.SS模型和等可靠度方法计算一致性以及以时间、降水为协变量的非一致性的设计洪水。结果表明:(1)以降水为协变量的非一致性概率模型好于以时间为协变量的非一致性和一致性的概率模型,其不仅能够模拟洪水序列的趋势,还能够反映洪水的波动变化。(2)龙潭寨水文站的一致性的设计洪水为269~423 m.(3)/s,总体大于非一致性的设计洪水(182~432 m.(3)/s)。(3)以降水为协变量的设计洪水更为合理。研究结果可为洪水灾害防治和水利工程设计等提供参考依据。

海上风力机结构体系长期经受波浪、风等水平循环荷载的作用,循环荷载的长期作用会引起桩周地基土体产生棘轮效应及形成密实沉陷区,研究长期循环荷载效应对风力机单桩承载特性的影响规律具有重要的工程意义。基于有限差分软件FLAC3D计算平台,建立风力机单桩的数值计算模型,与既有桩基试验开展对比验证模型的有效性;随后引入长期循环荷载效应引起的桩周密实沉陷简化模型,开展海上风力机大直径单桩的承载性能对比研究,探讨考虑与未考虑密实沉陷区时桩基的变形、弯矩、p-y(土体抗力-桩基水平位移)曲线的差异,分析长期循环荷载效应对桩基承载特性的影响规律。结果表明,密实沉陷对单桩的刚性转动点位置基本无影响,但在桩基埋置的浅层区域,桩周密实沉陷区对桩基水平位移影响显著,且引起桩基弯矩发生突变。
