Numerical analysis of liquefaction-induced differential settlement of shallow foundations on an island slope

The subway line will cross near the church St. Johann in the city. The foundation influence caused by tunnel construction from adjacent buildings will be simulated by software FLAC3D. And the feasible proposal of the construction will be resulted from the data which are collected from the field measurement and simulation. It plays an important role for coefficient of horizontal pressure K0 in simulating the geotechnical engineering. Comparing the data from the field measurement with simulation, the coefficient of horizontal pressure will be corrected. And the results of the simulation will be much closer to the real profiles.

Many road and highway have been constructed over the expansive soil in Java island without proper soil improvement for the subgrade. The behavior of the column on the expansive soil needs for study numerically and large scale. In this study, a numerical analysis is performed to study the effect of swelling on the deformation of the soil stabilized column supported flexible pavement. The main focus of the research is to obtain the deformation due to swelling and vehicle loading. The methodology including comparison the differential settlement of the soil stabilized column supported flexible pavement and unsupported flexible pavement as control model. The numerical analysis was modeled using finite element method. The simulations result that the column installation to support flexible pavement reduced the heaving and differential settlement of the pavement effectively. In case the overlay was performed for rehabilitation and maintenance of the pavement, the mini-columns can be installed before the overlay works. However, the conclusions of the study were limited to the result of numerical modeling that depended on the applied material model and volumetric swelling.

The Stability

Based on results of a deformation monitoring exercise, a numerical analysis was done to identify the causes of defects and assess the stability of a reinforced concrete bunker. Different scenarios were tested, among them the effects of coal lateral pressure on the wall, loading of different quadrants of the bunker, temperature differences and effect of differential settlement on crack formation. In calculating the coal pressure, classical theory presented by Rankine was used together with provisions of the design codes. Temperature differences are seen to have a significant effect on the stress distribution whereas differential settlement presents a major concern to the stability of the Bunker.
