ABSTRACT

Embankment construction in a very soft clay layer for transportation projects is common in many areas in Indonesia. One of them is the construction of a new double-track connecting Purwekerto and Kroya in Central Java. However, the challenge of this project was the existing track that must continue to operate while the new embankment was constructed. The project requirement was to limit the impact of the new tracks during construction on the stability and settlement of the existing railway embankment. Therefore, deep soil mixing (DSM) ground improvement technique with grid spacing was selected to increase the bearing capacity of the existing soil and reduce the settlement of the embankment. Numerical simulations using a 2D finite element program were performed to evaluate the performance of the deep soil mixing method in terms of factor of safety and settlements. The results showed that the stability of the embankment during static and seismic conditions satisfies the requirements. The settlements caused by the construction of the new embankment were remained within the allowable settlement during the construction and operational conditions. The deep soil mixing has successfully improved the stability of the embankment and limited the deformation of the existing railway track constructed on soft ground conditions; hence the train continued to operate during the construction.
