The superior performance and low cost of reinforced concrete(RC)has thrust it to be one of the most commonly used construction materials in the world.RC structures are exposed to a variety of factors that lead to its degradation during their operational existence,each of which contributes to reducing their service life,durability,and load bearing capacity.The longevity of RC structures is strongly connected to degradation processes,whose origin is environmental and/or functional.Among these processes is the evolution and growth of corrosion on the steel reinforcement.The corrosion of steel reinforcement has direct effects on the durability,safety,and useful service life of a RC structure.Safety of structural components is now commonly assessed using probabilistic methods.The reliability of an engineering design is an assessment of the probability that a certain design meets certain demands under certain conditions,or how likely its resistance will be able to sustain given loads.

随着智能手机的普及和通信设施的完善，通过分析居民的手机信令数据成为了获取城市交通出行和人口活动信息的有效手段。但是在实际应用中，考虑到成本和时间上的压力，现有的信令数据分析结果绝大部分都是基于单个运营商的数据得到的。由于无法确定不同运营商获得数据结果是否具有显著差异，使得只基于一个运营商的数据结果很难证明满足城市交通分析精度的要求。针对这一问题，本文从数据分析角度出发，基于东北某城市两个运营商同一
长洲水利枢纽已建成4 座船闸，是在通航环境复杂的西江河段建成的船闸群，是国内目前建成的规模最大的单级船闸群，最大船闸有效尺度340m×34m×5.8m.本文对船闸群选址、轴线位置、平面布置、改善引航道口门区水流条件的措施、输水系统、锚地布置、对外交通等方面进行了介绍，对其他枢纽船闸工程的总体布置具有参考意义.

混凝土桥梁分段施工技术是当今世界桥梁工程的主要发展趋势之一，桥梁预制节段拼装技术得到越来越广泛的应用。下部结构的预制拼装技术在强震区的研究还是比较少见。本文主要采用有限元方法研究不同位置灌浆套筒连接的预制拼装桥墩的抗震性能。研究发现采用灌浆套筒连接的预制桥墩各方面抗震性能与现浇桥墩基本相当，在合理的结构设计下，预制桥墩都可以满足抗震要求。

隧道掌子面帷幕注浆止浆墙是关系工程安全和注浆效果的重要因素。基于此，将止浆墙简化为标准矩形板结构，运用朗肯主动土压力理论和板结构的塑性绞线法相关理论，对止浆墙侧向受力进行分析，推导出了止浆墙安全厚度方程，得到止浆墙的定量化判据，最终揭示了止浆墙的受力机制。通过算例分析了同一注浆终压条件下，传统经验公式、卡尔梅柯夫公式和本文方法所确定止浆墙安全厚度之间的关系；分析了隧洞埋深、地下水压力对止浆墙安全厚
钢桁架塔杆件多，结构体系复杂，风荷载的确定往往依托风洞试验，因此，采用合理的试验模型对获得准确的风洞试验结果至关重要。以某测试钢管桁架塔大比例缩尺气弹模型风洞试验为背景，按照空气动力学弹性相似准则，采用离散刚度法，克服风洞测试段尺寸和来流风速受限、单个杆件尺寸细长难以模拟等困难，设计制作了钢管桁架塔全气弹模型。通过动力特性测试发现，模型自振频率和阻尼比值与理论值吻合较好，表明模型设计合理，满足风洞
