北京某商业办公楼项目地基基础设计

Foundation design of a commercial office building in Beijing

主要介绍了北京市朝阳区太阳宫乡某商业办公楼项目的地基基础设计。该工程由于涉及到CFG桩地基处理、抗浮锚杆、地源热泵同时存在的情况,加上场地条件限制等因素,使地基基础的设计相对比较复杂。着重介绍了确定基础形式时的综合考虑和方案比选过程、抗浮设计、基床系数的参数取值,以及本工程中地源热泵系统的应用情况,并针对地源热泵的竖向钻孔和水平横槽对地基承载力的不利影响所采取的多种措施。

The foundation design of a commercial office building in Beijing was introduced,including the subgrade treatment and foundation design,as well as the method for reducing the adverse effects of using the ground source heat pump system.
