摘　　要：双圆隧道由于渗漏水而产生沉降变形一直是严重威胁轨道交通结构安全的病害之一。从双圆盾构隧道结构构造特点入手,结合上海轨道交通某区段工程案例,分析由于渗漏水导致结构变形的原因和机理,提出双圆隧道渗漏水治理与变形控制的方案。Settlement deformation caused by leakage water is one of the serious diseases that have always threatened the safety of the rail transit structures for double-O-tube tunnels. From the aspect of structure characteristics of doubleO-tube tunnels and combined with Shanghai rail transit some section project case, the causes & mechanism of structure deformation by leakage water are analyzed, and finally, the scheme of leakage treatment & deformation control of doubleO-tube tunnel is proposed in this paper.
