摘　　要：塔式起重机基础形式可分为3种,针对现场实际情况及客观条件,选择一种经济、合理、安全的塔式起重机基础形式十分重要;因此塔吊基础形式选择及设计成为塔式起重机安装技术中的关键环节。在首都体育学院教学训练综合楼工程中因受拟建场地形及周边建筑物限制,塔吊位置只能布置在基坑南侧边坡及基础高低跨位置,需对基础做详细的选型及地基加固处理。介绍了该工程塔吊基础的设计与施工要点,通过基础沉降观测,塔吊基础不均匀沉降量观测值为4mm,满足塔吊的安全使用。The foundation forms of tower crane may be divided into three kinds.Based on actual situation and condition,a economy,reasonable,and safe tower crane foundation form is very important to be selected.Therefore,the selection and design of tower crane foundation form is the key point in tower crane engineering.Because of the complex terrain and limitation around Capital Physical Culture Institute teaching and training project,the foundation location is at the south of foundation slope with different elevations.Foundation selection and strengthening must be thought.The design and construction of tower crane under complex terrain condition are introduced.According to foundation settlement observation,asymmetry settlement observation value of tower crane foundation is 4mm,which meets the requirements of tower crane safety.
