Abstract

This research presents the monitoring results and their interpretation on load sharing of the pile foundation during the construction of a high-rise (124 m in height) building in Bangkok, in soft clayey ground. Axial forces in several piles, pore water pressure and earth pressures beneath the raft in a tributary area were monitored through the construction period of the building. The raft of the pile foundation in soft clayey ground can share the load up to 10-20% even though the foundation was designed using the conventional approach in which the raft resistance is ignored. The benefit from the return of ground water table as the uplift pressure is recognized. A series of parametric study by 3D-FEA were carried out. The potential of utilizing the piled raft system for the high-rise building with underground basement in soft clayey ground was preliminarily confirmed.

粘土桩基础中桩与筏板荷载分担的测量与分析
本文介绍了曼谷某高层建筑(高124米)在软粘土地基上施工过程中桩基荷载分担的监测结果及其解释。在整个建筑施工期间,监测了几根桩的轴力、支流区域筏板下的孔隙水压力和土压力。在软粘土地基中,即使采用忽略筏板阻力的传统设计方法,桩基筏板也能分担10-20%的荷载。认识到地下水位作为上扬压力的回归所带来的效益。采用三维有限元法进行了一系列参数分析。初步确定了桩筏体系在软粘土地基中具有地下地下室的高层建筑中的应用潜力。
