摘　　要：本文介绍了钢筋混凝土排仓结构在岩溶突水地质灾害下的结构可靠性鉴定,对于该排仓结构按上部结构、地基基础两个结构系统进行可靠性评定,其中上部结构包括仓顶、仓壁、仓底、仓下支承结构四个鉴定单元。对于受地质灾害影响的构筑物可靠性鉴定,主要按裂缝分项和整体侧移分项进行可靠性评定,并根据搜集的相关资料定量分析地下水流失引起的负摩阻力以及产生的下拉荷载对该筒仓结构的影响,可为工业构筑物在同类条件下的技术鉴定提供工程参考。The appraisal of reliability for reinforced concrete silos in line in karst water inrush accident,which includes two structure system parts of the upper structure and foundation,is introduced in this paper.There are four appraisal units in the upper structure,such as the top of silo,the wall of silo,the bottom of the silo and the supporting structure of silo bottom.Two items of assessment of cracks and integral displacement are the main steps of the appraisal of reliability for the silos in karst water inrush accident.And the influence of the silos under the the drop-down load caused by the negative skin friction is quantitatively analyzed according to collect information,which would be useful for similar project.
