摘　　要：分析了作业井架结构的极限承载力问题,对井架的失稳形式进行了分析,确定了井架结构的失稳形式属于极值点失稳,并通过结构几何非线性与材料非线性的双重非线性稳定性分析计算井架结构的极限承载力。对具有不同程度初始弯曲的井架进行了承载能力研究,得出了井架整体初弯曲程度与结构极限承载力之间的变化关系。The analysis of utmost load was made for mast structure.The under-balance was analyzed to verify what type of under-balance it pertains to.The analysis of double nonlinear stability of geometrically and material nonlinear was made to calculate the carrying capability of the structure.A study of carrying capability was made as well for the initial bending in some extent to obtain the function between mast initial bending and structure utmost load capacity.
