摘　　要： 成贵铁路客运专线某工程段采用SLJ900/32运架一体机在高铁隧道内架设常规跨度与非标准跨度预应力混凝土箱梁,对非标梁架设采取降低主支腿高度、增设变跨锚固点、安装测力传感装置等措施顺利完成施工任务。介绍了非标梁架设步骤、工艺改造措施等,对同类工程有借鉴意义。 A certain engineering section of the Cheng-Gui Passenger-oriented Railway uses the SLJ900/32-type beam-transpor- ting-erecting machine to erect both the normal-spanned and the non-standard-spanned pre-stressed reinforced concrete box beams inside the tunnel of a high-speed railway,in which case the main landing legs are shortened,the number of the span-var-ying anchoring points are increased,the side-force sensors are provided and some other technical measures are also taken,upon the basis of which the construction task of the project is smoothly accomplished. The beam-erecting procedures,the technically innovative measures and the like for the project are introduced in the paper-which may serve as a useful reference for other pro-jects of the same type.
