摘　　要：简述了３０ｔ煤炭抓斗装卸桥的结构形式及使用情况，说明了对该类结构进行承载能力计算的必要性，并给出了计算工况、载荷、主要计算结果及计算与实测两种结果的比较。在此基础上对结果进行了分析，得出了对安全生产有参考性的结论，也对结构计算所用的软硬件平台及计算模型规模进行了必要的说明。By brief instruction to the structural type and operations of the 30t Coal Crab Gantry Crane, this paper gives a reason to analyse the load-bearing capacity for this type of the structure. After then the calculation cases, the relative loads, the basic results and the comparison between the calculating results and the testing ones are given in this paper. Based on those, this paper gets some conclusionsworth to the safe operations. The soft-and-hardware for this analysis and basic information about the modeling are also stated bricfly in this article.
