摘　　要：基础的连接通常都是采用预埋地脚螺栓和预埋套管,对预留栓孔及预埋螺栓要求精度高,一旦某个部位精度达不到要求,将影响整套设备的顺利安装,其后处理极其困难,费用高昂。处理不当还容易造成质量事故。设备基础结构截面尺寸大,支撑高度大。对支撑体系有较高要求。本文通过实际工程机轮机基座施工工艺进行总结,以对类似工程提供参考。The foundation is usually connected with embedded anchor bolts and embedded bolt holes.The accuracy of the reserved bolt holes and embedded bolts is required to be high.Once the accuracy of a certain part fails to meet the requirements,the smooth installation of the whole set of equipment will be affected.The subsequent treatment is extremely difficult and expensive.Improper handling is also likely to cause quality accidents.The equipment foundation structure has large section size and large support height.There are high requirements for the support system.In this paper,the construction technology of turbine foundation is summarized through practical projects to provide reference for similar projects.
