目的探讨CT淋巴管造影（CTL）对淋巴管肌瘤病（LAM）淋巴回流障碍的诊断价值。方法回顾性分析21例临床和病理证实为LAM患者的临床及影像学资料，由2名医师对CTL的图像及其发生率进行分析。结果CTL示：（1）胸部异常征象：肺内多发含气囊腔21例，胸导管出口梗阻15例，纵隔密度增高13例，支气管血管束和小叶核心增厚11例，小叶间隔增厚13例，叶间裂增厚18例，肺脏实变或磨玻璃影7例，胸膜增厚19例，心包积液和心包增厚6例，气胸2例，胸腔积液21例，对比剂异常分布或堆积16例，纵隔和腋窝淋巴结肿大4例。（2）胸外异常征象：腹膜后淋巴管瘤或淋巴管平滑肌瘤16例，对比剂异常分布或堆积21例，腹腔积液10例，肠系膜水肿4例，肝脏或肾脏错构瘤5例，卵巢畸胎瘤1例，子宫肌瘤2例，骨骼内异常密度7例。结论LAM很可能是一种全身性系统性淋巴回流障碍性疾病，肺部囊性变只是LAM全身病变中的一部分。CTL能够明确淋巴回流障碍的部位、范围及程度，为临床诊断及治疗LAM提供了影像学依据。

斜拉索作为斜拉桥结构的主要受力构件,对桥梁结构的受力影响重大。本文以实验室独塔斜拉桥模型为研究对象,展开基于索力实测的斜拉桥结构有限元模型修正技术研究。建立基于ANSYS平台的模型斜拉桥板壳模式的初始有限元模型,对模型斜拉桥进行静力荷载试验,测试各工况下的斜拉索索力,并以实测索力为主要修正对象,位移响应为次要修正对象,基于结构参数进行灵敏度分析,得到模型斜拉桥的主要和次要修正参数。运用ANSYS优化模块,对模型斜拉桥初始有限元模型进行修正,修正后的有限元模型各工况下计算索力、位移与实测索力和位移吻合良好。修正后的结构参数物理意义明确,修正后的有限元模型可以作为基准模型,用于后续的损伤识别研究。所提方法可供大跨斜拉桥结构有限元模型修正参考借鉴。

我国城镇化的快速发展伴随着大量的基础设施建设,隧道建设成为城市地下空间开发中的重要组成部分。由于隧道工程其特有的结构复杂性、施工隐蔽性和施工组织设计的综合性,使得隧道施工周期长、造价高且施工技术要求高,导致施工过程中的不可控风险因素众多。以往风险评估主要依托工程师的施工经验为主,使得风险评估结果具有一定的主观性。土岩复合地层中土压平衡盾构掘进风险评估具有复杂、难以建模的特点,以珠海市某盾构隧道工程为背景,基于现场的监测数据和施工工程经验,运用云模型理论,对盾构机在土岩复合地层中的掘进风险进行研究。根据实际工程概况,确定总推力、刀盘扭矩、螺旋机转速、土压力、泡沫注入量和泡沫注入压力等6个影响因素,将监测数据划分为5个等级,提出基于云模型融合多参数的盾构掘进风险等级评价模型。提出的模型将盾构掘进的多源数据进行有效融合,通过计算标准云与待识别云的相似度得出隧道掘进风险等级,评估结果具有可靠性和可操作性。降低了盾构隧道施工事故的发生并提高了施工效率。该模型评估结果与现场实际情况相符,可为土压平衡盾构机在复杂地层中的掘进风险评估提供参考。
