Test-bed was constructed in Honam High-speed railway due to evaluate the suitable infrastructure for operation of 400km/h level speed. To evaluate performance of roadbed in test-bed, several sensors installed in the standard roadbed, soft ground, transition zone as bridge and earthwork. In contrast to existing long-term monitoring, system developed was designed and builted on site to log-time operation automatically. Therefore, the measured data collected monitoring system and analysis results can be databased continuously from construction to operation of railway for study design criteria about long-term behavior of roadbed.

In this paper, the filed test procedure for evaluating the performance of track structure for additional Speed-Up test on Test-Bed Section(KP 100∼128km Osong starting point). The behavior of track system corresponding the speed up of train will be identified by the analysis of the measured data.

In this paper, sensors and equipments for monitoring the weather in test-bed of Honam high-speed railroad are introduced, and integrated monitoring system linked to weather information and its management plan are suggested.

In this study, it explains briefly the test procedure for evaluating the performance of roadbed in test-bed section of Honam high-speed railway.

In this study, it explains briefly the test procedure for evaluating the performance of track and bridge in test-bed section of Honam High-Speed Railway.

Recently, power distributed high-speed train with 430km/h(HEMU-430X) has developed in korea, 2012. However, the development of the train alone can not achieve the speed of high-speed rail system. So it needs the development of infrastructure system. In this paper, the project named “Application & technology development of high-speed rail infrastructure for 400km/h-class” being promoted in december 2010 will be introduced comprehensively.

In this paper, RF receiver for CDMA system which has 10 MHz in the channel bandwidth has been designed and fabricated. The designed and fabricated RF receiver is shown useful in operation and the performance has been confirmed by experiments. The results are to be used for establishment of a broadband CDMA wireless access specification standard for WLL system in 2.3 GHz band.
