  With increasing collapses of bridge structures and popularized utilization of long-span bridges,worldwide bridge performance assessment is of importance in emerging and future bridge management industry.A reliable and visualised bridge performance assessment method can promote serviceability and safety of bridges because bridge management supervisors usually take it as guideline to make decisions.Although new technologies,building information modelling (BIM),laser scanning by point clouds and structural health monitoring,have gained rapid development in recent years,present bridge performance assessment are still mainly based on practical experience and on-site inspection.On the other hand,the collected data obtained from SHM system needs a smart data interpretation approach due to the usage of data is still limited in most of the current bridge performance assessment methods.In this regard,this paper presents a framework of BIM-based bridge performance assessment method.Firstly,the existing BIM implementation in Australia is introduced in Sectior.2.Secondly,automated as-built bridge modelling by laser scanning technology is introduced in Section.3.Finally,a framework of BIM-based bridge damage detection and localization method is introduced in Section.4.We demonstrate the advantages and potential future of BIM-based bridge performance assessment on bridge structures.

玄武岩纤维增强复合材料(BFRP)锚杆是一种由树脂和玄武岩纤维复合而成的新型材料,与传统钢筋相比具有强度高、耐腐蚀性强和抗震性能优越的特点.基于不同直径BFRP锚杆在不同强度围岩材料中的室外拉拔试验,利用改进的应变测试元件对锚固系统内部空间应力传递现象进行分析,为BFEP锚杆的推广应用和设计提供理论基础.试验结果表明:同种围岩材料中,锚固系统界面应力沿轴向和径向的衰减速度均与BFRP锚杆的直径有关
囊式扩体锚杆技术是一项具有技术、经济、环保优势的新型扩体锚固技术,应用该技术体系能够大幅度提升锚固结构体系的安全性与耐久性.经过大量的试验研究和工程实践,岩土锚固工程界逐渐认识了深埋囊式扩体锚杆的承载变形性状所特有的加工硬化特征,且扩体锚固段端承力对锚杆承载力拥有决定性的贡献.结合宁波工程项目进行了囊式扩体锚杆现场足尺试验研究,并分析讨论了这种新型扩体锚杆的试验结果及其工作特性.
水利水电建设中,无论如何选择坝址,都会遇到错动带处理相关问题.针对错动带的处理,根据不同的岩层,出露于不同的部位而处理的方案也不尽相同.在大型地下洞室群内遇到错动带,严重影响洞室围岩稳定,一般采用综合的处理技术进行加固.本文从白鹤滩水电站左岸地下厂房C2错动带的地质构造、成因及产状的分析着手,分析对白鹤滩左岸地下厂房上下边墙稳定的影响程度,再分别从开挖回填混凝土置换、高压对穿冲洗、预应力锚杆、钢筋

地聚合物混凝土的缩重合反应伴随着水的排出,而且目前还没有降低碱激发剂水溶液用量的添加剂.因此,常温养护的地聚合物混凝土的干燥收缩很大,容易造成收缩裂缝.为促进地聚合物混凝土的实用化,作者在开发了地聚合物缓凝剂之后又开发了适用于地聚合物的收缩控制剂.本文将详细介绍地聚合物收缩控制剂的添加对粉煤灰和高炉矿渣复合使用型地聚合物混凝土的流动性,可使时间和强度的影响以及常温养护时体积变化的减少效果.
混凝土结构隐蔽工程的施工过程往往难以人工观察测量,因此而导致隐蔽工程的施工质量难以通过常规工程的过程控制理论和方法来保障.针对隐蔽工程施工质量过程控制系统和方法缺乏的挑战,本文提出了利用惯性测量单元对隐蔽工程的施工全过程进行实时监控与记录的理论和方法.该系统包括数据搜集、处理和可视化三个模块,可对建筑构件、材料、施工设备及工具、施工人员等的位置和姿态进行定位和追踪.同时该系还整合了环境可测变量,例
