Abstract

Sai Gon South is the gateway area being focused on developing urban infrastructure of Ho Chi Minh city. However this area have a low-lying terrain and weak geological structure. Therefore the subsidence problems are very serious now due to the urbanization. There is few research obtained to the effects of subsidence in this area the study has been carried out to assess the current situation and forecast the ground subsidence in this area. The study used the geo-statistics method of Kriging and calculation method for subsidence. The interpolated results of 167 boreholes showed the geologycal weakness of the soil layer from 6.5 to 35m which has correlation with the subsidence. (Coefficient r2 = 0.7).
