There is a need to extend the life of many existing railway bridges.To facilitate this is one of the objects of the EC-FP7-Project MAINLINE,covering a period from 2011 to 2014,http//mainline-project.eu.New or improved technologies are investigated to help with this.

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
A reliability-based safety assessment method is proposed for bridges in the Korean expressway.In addition to the current Korean guideline for the safety assessment,some available international safety
Prosperity and quality of life of our modem society is also based on a well-established road network for movement of goods and passenger traffic.Bridges are a vital,but also vulnerable part of this ne
Structural health monitoring provides an efficient way to monitor and evaluate the performance of infrastructure,especially in structures that are more than 100 years old.In New Jersey,most of the rai
The history about the modern bridges in Korea dates back over 100 years to when the first modem bridge was built over the Han River in 1900.However,the oldest bridge does not exist any longer but the
Probability based safety concepts are employed in developing a design manual for long-span cablesupported bridges in Korea.In order to offer flexibility to the owners and the designers,the target safe
With the development of high-speed railway,bridge vibration induced by moving trains has become an interesting topic in the field of civil engineering.In recent years,a huge amount of researches on th
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
Growth in demand for rail transportation across Europe is predicted to continue.Much of this growth will have to be accommodated on existing lines that contain old infrastructure.This demand will incr
With passenger and freight traffic predicted to rise by around 19% and 13% respectively across Europe between 2000 and 2020 (COM 2006),existing railway assets will need to sustain greater volumes of t
