摘　　要：为解决2500t环轨式起重机的抗倾覆稳定性验算问题,提出了验算模型并做了验算,为环轨式起重机的设计提供一定理论支持。分析总结了3种最危险的情况,同时考虑风载荷、配重载荷、结构自重及吊重等对稳定性的影响,建立其抗倾覆稳定性的验算模型;介绍了风载荷及配重载荷的计算方法,利用验算模型,对2500t环轨式起重机进行了抗倾覆稳定性的验算。结果表明:3种危险情况均稳定,工作状态最长臂架最小幅度满载运行时的倾覆力矩最大。To solve the checking computation problem of 2500t ring-rail crane, this paper has built the mathemat- ical models for checking computation and provided a certain theoretical support for the design of such cranes. Based on a consideration of wind load, balance weight, dead load and cargo weight, three dangerous conditions are summarized, and each checking model is established at the same time. This paper also presents the computing method of wind load and balance weight for checking computation. The results show that three dangerous conditions are all stable, and the maximum overturning moment appears in working condition of the longest jib, minimum radius and full load.
