摘　　要：针对大直径盾构在地下吊装、拆卸时所面临的实施空间小、设备尺寸大、地下环境复杂等问题,设计了一种带可升降支腿的双梁门式新型起重机。应用Solid Works建立可升降支腿的三维模型并进行有限元仿真分析,同时,针对液压升降柱在起重机箱座不同位置分布的情况进行静力分析和模态分析,得出最优布置方案,使起重机的结构设计更加安全可靠。In view of the problems during underground lift,assembly and disassembly of large-diameter shields suchas small operation space,large equipment size and complex underground environment,a new double-girdergantry crane with liftable outriggers is designed.Solid Works is used to establish a three-dimensional model of the liftable outriggers and conduct finite element simulation analysis.At the same time,static analysis and modal analysis are carried out for the distribution of hydraulic lifting bollards at different locations of the crane base to obtain the optimal layout plan,making the structural design of the crane safer and more reliable.
