摘　　要：顶管掘进机的选型是顶管工程施工成败的重要因素之一。顶管掘进机选型不当,可能造成顶管推进困难,甚至导致顶管机头报废等情况,造成重大经济损失,严重影响施工进度。本文结合工程实际情况,对不同类型顶管掘进机适应的管道直径、埋深、地层情况、经济特性等方面进行综合分析,对顶管掘进机的选型具有参考价值。The selection of pipe jacking machine is one of the important factors for the success or failure of pipe jacking construction.Improper selection of pipe jacking machine may cause advancing difficulties and even lead to scrap of pipe jacking machine head,result in significant economic losses and seriously affect the construction progress.Combined with the actual situation of project,a comprehensive analysis was made on the pipe diameters,buried depth,strata conditions and economic characteristics adapted to different types of pipe jacking machines,so as to provide reference for the selection of pipe jacking machine.
