【摘要】 概述了软土地层盾构隧道纵向沉降引发的各种问题,分析了有关隧道纵向沉降方面的主要研究成果。其中包括各种软土隧道纵向结构的理论解析分析模型,土-隧道结构共同作用的解析模型等。在介绍目前研究不足的基础上,指出需要通过相似程度更高的模型试验、更多的现场实测数据、与实际土层性质更吻合的地基模型,进一步研究软土地层盾构隧道的纵向沉降特性、纵向结构性能。更多还原

【Abstract】 Problems caused by longitudinal settlement of shield tunnel in soft ground, the main research achievements in this field are introduced, such as the longitudina l t heoretical analysis model of shield tunnel, the interaction analysis model betwe en soil and tunnel structure. The authors argue that more studies on longitudina l settlement behaviors of tunnel are needed, which require more tests, more in-site records and more improved ground models.更多还原
