剪力块在香港某高层建筑基础设计中的应用

APPLICATION OF DREDGE WALL IN FOUNDATION DESIGN OF A HIGH-RISE BUILDING IN HONGKONG

对于建筑在边坡上的高层建筑,桩基础设计除满足桩基承载能力极限状态和桩基正常使用极限状态的要求,还须保证边坡的稳定性。以香港某高层建筑为工程背景,将剪力块用于该建筑基础设计中,以抵抗风荷载产生的侧向力和扭矩,限制边坡岩土体的位移和变形,从而确保了靠近边坡的高层建筑基础设计中边坡的稳定性,得到的结论可为类似工程提供参考。

For the high-rise building built on slope, the foundation design meet not only the requirement of limit bearing capacity of foundation and limit state of normal usage, but also the stability of slope. A high- rise building in Hongkong is taken as the engineering background, the dredge wall is applied in the foundation design to resist the wind-induced lateral stresses and torsion moments, so that the displacement and deformation of the rock mass of slope can be limited to make sure the stability of the slope in the foundation design of the high-rise building built on slope. The conclusions obtained can give guidance for the similar projects.
