Application Of PLAXIS 3D Software To Simulate The Deformation Of Marine Clay Under the Raft Foundation Due to The Influence of Groundwater Levels at Different Depths
摘要
In recent years, researchers presented the Raft Foundation deformation (settlement) on the Clay ground by many methods in the worldwide. The present study’s objective presents the Topographic Conditions’ influences on the deformation of the marine Clay ground under the Raft foundation. The maximum vertical Displacements (or vertical settlement), DDis of the ground show 29.41 cm according to the minimum Young’s modulus Esimu, YEsimu was 290 (× 102 kN/m2) at 20.0 m depth with cohesion force, Fcf was 34.5 kN/m2. The minimum displacement, DDis was 11.75 cm at 16.0 m depth with the maximum active and passive pore pressure, Pactivepassivepore was 1400 kN/m2. Total Cartesian strain εCartzz = 0.09023 m at the Seawater level depth Dseadep = 9.0 m, with the Displacement PDis = 0.212 m. The Incremental Cartesian strains ΔεInCartzz = 0.0053 m at the Seawater level depth Dseadep = 9.0 m, with the Displacement DDis = 0.212 m. Moreover, the Stages Cartesian strains ΔεInCartzz = 0.0053 m at the Seawater level depth Dseadep = 9.0 m, with the Displacement PDis = 0.212 m. The maximum value of total volume strains, PεTotalvolume, Stage volume strains, PεStagevolum obtained 12.7 cm compared with the Incremental volume strains, PΔεInCartzz = 0.4721 cm according to the Displacement DDis = 29.41 cm. Moreover, the soil deformation resistance increases gradually when the loading increases, this results in the Raft foundation deformation being reduced remarkably. In Conclusion, the present study results supply useful references to the field of Geology and civil engineering to minimize and save labor costs, survey time, design, calculation, etc., in the future.
