甬舟铁路富翅门公铁两用跨海大桥采用主跨388 m高低塔公铁平层挑臂式钢箱梁斜拉桥,为世界上最大跨度的高低塔公铁平层合建斜拉桥。为研究适用于大跨度高低塔公铁平层合建斜拉桥最优结构体系,结合富翅门公铁大桥结构不对称的特点,对5种不同类型半飘浮体系、塔梁约束体系进行比选研究。通过对5种约束体系在静、动力荷载作用下的桥塔弯矩、桥塔位移、主梁位移对比分析,推荐采用高塔侧设置固定支座、矮塔侧采用活动支座的约束体系,该体系抵抗纵向荷载能力强、释放体系温度变形差,与常用的半漂浮体系相比,在静、动力荷载作用下桥梁总荷载效应小,具有良好的静动力性能,其中静力作用下两桥塔塔底总弯矩降低15%,两侧梁端总位移降低51%,两塔顶位移减少29%;动力作用下两桥塔塔底总弯矩相当,两侧梁端总位移降低76%。

陕西蓝田水陆庵诸圣水陆殿南稍间横墙西壁有一尊佛像坐于孔雀背负的莲台之上,背有孔雀尾佛光。这种骑孔雀的佛像非常罕见,关于这个佛像的图像志目前学者们争议比较大,有人认为是孔雀明王,有人认为是文殊菩萨,还有人认为就是阿弥陀佛。笔者在实地考察的基础上,结合诸家的说法,运用图像学的方法,对其进行辨认和疑点考量。经过文献和图像两方面的考订,认为其身份应为阿弥陀佛。

研究目的:甬舟铁路金塘水道主航道桥建设环境复杂,墩位处最大水深49 m,设计流速3.14 m/s;设计风速42 m/s,最大浪高8.89 m;海底岩面起伏较大,覆盖层厚薄不均。本文就金塘水道主航道桥深水浅覆盖层地区和深水厚覆盖层地区基础方案展开研究,探寻适用于不同地质条件下的深水跨海桥梁合理基础类型,以期为复杂环境下跨海桥梁深水基础设计提供借鉴。研究结论:(1)跨海桥梁深水基础选择应结合水文、气象、地质、通航等边界条件,从结构受力、经济性、可实施性、水流适应性及通航要求等方面综合确定;(2)深水浅覆盖层地区应优先采用整体刚度大、承载力高的设置基础;(3)深水厚覆盖层地区应优先采用整体刚度大、承载力高的沉井基础;(4)水深30 m以上桥梁基础采用桩基础施工难度大、经济性差,设置沉井基础、沉箱基础、复合基础,沉井基础应为复杂恶劣海洋环境下跨海桥梁优先考虑的基础形式;(5)本研究成果可为复杂环境下跨海桥梁深水基础设计提供参考。
