摘要
对已有的大直径钢顶管弹塑性分析方法进行了改进和完善,并通过控制管壁截面的可靠指标β来保证"弹塑性分析"的安全度.之后,对软土地段的大直径钢顶管进行了较为全面的弹塑性分析,得出了一些有参考意义的结论,并将本文建议的"弹塑性分析"方法应用于实际工程,取得了较为合理的结果,同时也提出了需要关注的问题.
It is perfected that the elastoplastic analysis of large diameter steel pipe jacking in literature [3].By using limit reliability index β of pipe wall section,the safety degree of elastoplastic analysis is guaranteed.On this basis,the comprehensive elastoplastic analysis of the large diameter steel pipe jacking on soft soil foundation is made;and the theoretical results have been applied to actual engineering.The reasonable result has been acquired;and some suggestions are proposed.
