A failed embankment on a cement deep mixing (CDM)-formed column–improved soft clay deposit in Saga, Japan, has been reported and analyzed. Based the results of field investigation numerical simulation, postulated failure mechanism is that columns under section by bending (tension), which caused whole system to collapse. However, not necessarily checked current design process Japan. In addition, it found limited number all-core boring checks as adopted Japan cannot guarantee quality all...
Bending failure mechanism of column inclusions in soft clay deposit under embankment loading has been investigated by three dimensional (3D) finite element analyses. Firstly the effectiveness numerical procedure verified comparing simulated and measured results a centrifuge model test reported literature terms lateral displacement, settlement, bending moment column. Then effects size improved area from toe toward center embankment, stiffness column, length on maximum have numerically. The...
Single-timber piles were used as the pile foundation of small-scale buildings in soft ground Saga lowland, Japan, where differential settlement occurred. The tip timber was required to reach supporting stratum at a greater depth overcome problems. To stratum, these are connected with several joints. However, there is no detailed study describing strength jointed-timber (JTPs) and their material specifications. This describes specifications materials then explains laboratory tests that...
