Earthquake Activities and Hazards along Railways in the Mainland Southeast Asia

Abstract

In the future, there are plans to construct the many rail transportation in the Mainland Southeast Asia e.g. double rail and high speed rail. This senior project for estimate the seismic hazard along the railways in the Mainland Southeast Asia and specific the routes that have a risk for seismic hazard. This project use 2 methods for estimate the seismic hazard. They are Deterministic Seismic Hazard Analysis method (DSHA) and Probabilistic Seismic Hazard method (PSHA). The PSHA method use Building Code standard (2% POE 50 year and 10% POE 100 year) and JSCE standard (5% POE 50 year and 100 year). From the estimated, the railways in the western of the region have high peak ground acceleration (PGA). From DSHA method, the maximum PGA values is 0.46g near Hinthada station in Myanmar. By the PSHA method 5% POE 100 year, the maximum PGA value is 0.85g near Hinthada station in Myanmar. There are 8 lines that have risk for seismic hazard by Eurocode 1998-8 standard. The lines are all line in Myanmar, Vientiane–Khunming line in Laos and Chiang Mai–Bangkok line and Bangkok–Namtok line in Thailand. The lines that have risk include double rails and high speed rails.
