" The transportation or railway system constructors usually, wherever possible, build the transportation system on the ground surface and avoid the necessity of underground tunnelling. However, this is not always possible. In many locations, such as mountainous area, hilly area or urban area, the underground tunnelling have to be built. The main problem of underground tunnelling is the soil stability around the tunnel, and the problems continue to mount for long and big tunnel. Therefore in ... "

" ABSTRACT
The development and extension of large cities creates a need of multiple shallow tunnels in the soft ground of built areas. Excavating a tunnel generates ground displacements and deformations which can affect existing buildings and services in urban sites and can lead to unacceptable damages. Prediction of the ground settlement caused by the tunnel excavation has been a major engineering challenge.

A numerical simulation using finite element method was implemented in the aim of ... "

" The bearing capacity of footings on level ground can be predicted by different calculation methods, using the results of laboratory or in situ tests. In the other side the effects of proximity to a slope are poorly understood. This study was performed as a research on the bearing capacity of foundation on slope, in particular the influence of the internal angle of. friction (Φ), the cohesion (c) of the soil and the eccentricity of the load ...

" This thesis presented a numerical study of the improvement of soft soil using columnar inclusions. Review of analytical studies has been concentrated to British Standard BS8006, modified Terzaghi theory, and arching theory. Numerical model in this study is using FLAC3D code to generate 3D model. The materials properties uses in this model refer to typical values. Some of important design variables have been considered in our parametric study. The most efficient platform thickness is lm ...

" ABSTRACT
Nowadays, the ways, how to solve the mass transportation problem in the big city become the major problem for the government. Some difficulties come when the mass transportation facilities can't be build at the ground surface because many buildings and services will be disturbed. For avoiding that, the mass transportation facilities usually are built in the underground. It means that we have to excavate the underground to make a tunnel. Excavating a tunnel generates ground ... "

" ABSTRACT
The finite element method has been applied to the study the behavior of vertically loaded single micro pile, the nine piles in a close group, the three piles in a row group in a homogeneous non linearly behavior medium, that is cohesion less soil.

Bidimensional and axis metric elements have been used in the analysis to determine the stress and the strain state in the soil around the piles and the deformation of ... "
