| 摘 要： | 随着国内外盾构隧道的大量建设和运营,盾构隧道纵向不均匀沉降问题日益凸现,从而引发隧道渗水漏泥、结构局部破坏等现象。文中对隧道产生纵向不均匀沉降的原因进行了分析。针对影响隧道沉降的各个因素,采用等效轴向刚度模型,并应用弹性地基梁理论进行计算分析,得出相应的沉降曲线,为软土盾构隧道纵向设计提供理论支持。

| Abstract: | With the construction and operation of shield tunnel at home and abroad,the problem of uneven vertical settlement of shield tunnel is increasingly obvious,and thus causes the phenomena of water and soil leakage and partial structural deterioration.This paper analyzes the reasons of uneven vertical settlement of shield tunnel.The each influencing factor of tunnel settlement is simulated on the equivalent axial rigidity model and calculation and analysis are carried out using the theory of elastic foundation ... |
