The subsidence prediction due to load characteristics of underground structures in soft soil in Ho Chi Minh City

Abstract

Metro line No. 6 in Ho Chi Minh City is the stage of preparation for construction investment. Ho Chi Minh City has weak geology which construction can cause surface subsidence affecting the surrounding buildings above. Studying and forecasting of subsidence of the surrounding ground surface when constructing underground is an important issue for engineers. The article presents predicting land subsidence in the influence of external load such as pile foundation, increased load due to construction or change of transport infrastructure to twin tunnels to analytical and numerical methods.

Keywords: Twin tunnel; surface settlement; Plaxis; soft soil.
