固定式塔式起重机抗倾翻稳定性和基础设计计算

Calculation on anti-overturn stability and foundation design in fixed tower crane

验算固定式塔式起重机抗倾翻稳定性应对塔机的基本稳定性、动态稳定性、向后倾翻稳定性、安装稳定性等工作状态和暴风侵袭非工作状态进行计算.依据塔机抗倾翻稳定性条件设计混凝土基础,浇筑混凝土基础时应严格按制造单位提供的基础图施工.用该文的计算方法设计的塔机基础能满足固定式塔式起重机的抗倾翻稳定性要求.通过验算固定式塔式起重机不同工况下的抗倾翻稳定性,为塔机基础设计提供了可靠的理论依据.

To test the anti - overturn stability of a tower crane, it is necessary to calculate its basic stability,dynamic stability, back- overturn stability and its installment stability under the operating and non -operating states.Concrete foundation is designed under the condition of anti - overturn stability. When pouring concrete, construction is strictly implemented in accordance with the design drawing provided by the production unit. The tower foundation basedon the calculation method of this paper will meet the demands of anti - overturn stability. Through testing the anti - overturn stability under the different operating states, it proposes a reliable theoretical basis for the tower foundationdesign.
