摘要
根据各设计单位和井架的使用单位对不均匀沉降对井架影响的反馈情况,在《矿山井架设计规范》修订过程中,规范编制组就地基不均匀沉降对钢井架的影响开展调研总结。通过对不均匀沉降产生的原因分析,研究不均匀沉降对不同井架类型的内力及变形影响,探讨了原《矿山井架设计规范》(GB 50385—2006)相关条文的合理性,并提出了修改意见。
According to the feedback from design institutes and headframe users about the impact of differential foundation settlement on headframe, during the revision of ＂Code for design of the mine headframes＂, the concilliation panel carried out a special investigation on the issue. Through analysis on causes of differential settlement, influence of differential settlement on internal force and deformation of different headframes, the paper discussed the rationality of ＂Code for design of the mine headframes＂ （GB 50385--2006） , and put forward amendments.
