Measuring bridge deflection under dynamic loading is useful to understand structural behavior as well as to assess health condition.However,the conventional approaches for the deflection measurements in largescale bridges are challenging as they typically require fixed reference points that may be often unavailable in the fields.Alternatively,indirect estimation methods have been developed; other measurements such as acceleration or strain are first obtained and subsequently transformed to displacement.As the acceleration and strain are conveniently measured,the indirect estimation methods are considered to be effective and practical while they have in general lower accuracy in estimation compared to the conventional direct measurement.

泥水平衡盾构中，泥浆环流系统是利用管道输送渣浆的系统，主要利用泥浆的流动带走盾构机切削下来的渣土，达到盾构机出渣的目的。盾构机施工时，随着盾构机的掘进，隧道长度逐渐变长，输送泥浆的管道也必须相应延伸，同时管路上阀门、弯头数量也会逐步增多，这也必将导致输送系统的管路压损逐步增加，管路的压力损失直接影响到输送系统渣浆泵扬程的选择。文章从管道直径、流量、渣浆密度，以及阀门、弯头等因素出发，对管路压力损失
TRIZ创新理论是当前世界上最受欢迎和最有成效的创新理论之一，加强TRIZ理论的研究和提高其应用水平已成为有效提高个人和团队创新能力的重要方法。本文针对泥水盾构的泥浆门密封存在的问题应用TRIZ理论进行了设计改进：首先对泥浆门密封存在的问题进行技术矛盾的描述和参数转化，然后运用矛盾矩阵筛选出最接近的创新原理，在创新原理的指示作用下同时结合工程实际不同方案进行比较分析，最后得到了较合理的问题解决方案
CPⅢ网是指高速铁路测量中的轨道控制网，一般在线下工程施工完成后施测，是轨道铺设和运营维护的基准。本文把CPM技术引入城市轨道交通领域，通过提前布设，可起到代替调线调坡控制网、轨道基标网以及运营维护网并做到三网合一，本文阐述了相关试验并做总结。轨道基础控制网吸取了高铁CPⅢ中的核心理念：强制对中、自由设站、自动测量、无人工误差、相对精度与绝对精度融合统一，在保证绝对精度的同时，以提高相对精度为主要
