This paper presents the experimental results of consolidation properties of soft soil in Ho Chi Minh City of Vietnam. Forty-two samples were collected from different locations and were determined in the laboratory by Oedometer test. The results showed that the coefficient of consolidation of soft soil varies from 0.052.10-3 to 3.3.10-3cm2/s, otherwise the compression index changes from 0.156 to 1.703, soil is in a normally consolidated or over the consolidated state. These properties also change differently with depth. It also indicated that the compressive index of soft soil has a fine linear relationship with the liquid limit، water content, and void ratio. The coefficient of consolidation of soft soil decreases with the increase of compression pressure. These parameters are basic for calculating the settlement of underground structures in Ho Chi Minh City.

Complex Issue

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.
