The Vietnamese Society for Soil Mechanics and Geotechnical Engineering (VSSMGE), the Ho Chi Minh City University of Technology (HCMUT) and the National Taiwan Univ of Science and Technology (NTUST) will organize the one-day seminar on Numerical Analysis in Geotechnics (NAG2018), on 22nd March 2018, in Ho Chi Minh City. A half-day study tour to HCMC Urban Railway Construction Project – Line 1 (Ben Thanh-Suoi Tien Section) will be held on the next day, 23rd March 2017. This is the second time the international seminar NAG is organized in Vietnam. The first event NAG2015 was held on 20 August 2015 in Hanoi, with more than 120 attendees from seven countries and territories, including Singapore, Thailand, Taiwan, Canada, France, China and Vietnam.Continuing the success of the first event, NAG2018 will create a forum, where the users of different numerical methods/computer codes can exchange their experience and knowledge relating to the use of numerical methods in geotechnical engineering, including engineering applications and scientific achievements.
