In recent years, there has been a rise in the construction of expansive underground structures and shield tunnels with exceptionally large diameters. These projects introduce unique challenges regarding their impact on surrounding soil structures, which differ from those typically encountered conventional tunnels. However, existing body research this specific domain remains insufficient. When s...

Abstract The main problem of road construction on saturated soft soils is due to their low bearing capacity and large settlement. One the solutions such problems install piled box culverts-geofoam. In this study, pile culvert-geofoam was modelled as raft foundation. This experimental study conducted by making a prototype file foundation gradually loaded with maximum vertical load 20 kN. Differe...

In order to get a more safety and economic foundation, finite element method was performed for piled mat cap strip by the software of STAAD. Through analysis, plate distribution region bending moment shear stress were researched; meanwhile, considering compatibility deformation plate, how chose design value researched. The result showed that: single is not representative, average 9 plates (3x3 ...

The uplift of the raft foundation of reinforced concrete buildings, and the consequent partial loss of contact between soil and foundation, is a possible effect of an earthquake. Actually, reinforced concrete buildings with raft foundation are commonly used in nuclear power plants. In this context, some simplified approaches for uplift evaluation have been proposed in the past and are still use...

The paper presents typical phenomena which can occur due to cyclic loading in granular soil. Numerical analysis with different material laws shows the challenges to simulate the ground behaviour realistically. Results of numerical analysis by means of the Finite-Element-Method are presented and the limitation of material laws discussed.
