A STUDY ON BEHAVIOR OF TUNNEL IN SOFT SOIL CONDITIONS UNDER INFLUENCE OF EARTHQUAKES IN HO CHI MINH CITY

Abstract

Due to economic development and traffic congestion constraints, HCM City has implemented urban railways since 2007 and is currently constructing the underground metro line No 01. So far, general constructions and tunnel in particular in Vietnam is a complex issue, especially in the specific soft soil conditions of Ho Chi Minh City. In order to study the behavior of the tunnel during the earthquake, this paper compares an Imposed Seismic Ground Deformation method (ISGD) and the acceleration diagram method in calculating the tunnel affected by the earthquake in soft soil of the area of Ho Chi Minh city.
