| Abstract | The prediction of ground movement caused by underground construction is one of the most important and difficult problems in the design and underground construction in urban area. The ground movements were summarized with respect to influencing factors, namely: the soil stratigraphy, tunnel geometry, TBM face pressures, the operation of TBM and the presence of adjacent structures.
This study showed results of the prediction of the ground movements due to the Earth Pressure Balance Shield tunnelling in the Ho Chi Minh Urban Railway Line 1 project.
Analytical methods, numerical methods and empirical methods are usually adopted to predict ground deformation. However empirical methods, derived from field observations are widely used. They are based on the assumption that the ground settlement can be described conveniently by a Gaussian distribution curve. To investigate the reliability of empirical solution, a numerical analysis has been carried out by the Finite Element Method using Plaxis software.
The result comparison between the empirical analysis and the numerical analysis shows a good agreement and suggesting some choices for the parameters to adopt in the empirical solutions.
It also presented the assessment on potential effects on near by structures caused by tunnelling in Ho Chi Minh City |
