摘要:
随着城市轨道交通网络的进一步发展,大量的地铁盾构隧道临近甚至紧贴铁路箱涵桥建设。本文以北京地铁某典型区间隧道下穿铁路箱涵桥工程为例,应用数值模拟的方法,对盾构隧道下穿铁路箱涵桥的变形响应进行了研究,着重分析了注浆加固效果及沉降缝两侧的变形机理。研究结果表明:(1)盾构隧道下穿铁路箱涵桥过程中,沉降监测点产生影响的纵向水平区间约为监测点前3D(D为盾构隧道直径)至监测点后3D;(2)盾构隧道下穿铁路箱涵桥过程中,沉降缝两侧箱涵会出现较大差异沉降,易对桥体上方列车的运营安全造成影响;(3)盾构隧道穿越铁路箱涵桥前,对盾构隧道拱顶进行注浆预加固,可在一定程度上控制桥体沉降及沉降缝两侧差异沉降。
Abstract:
With the rapid development of urban subway network in China,a large number of subway shield tunnels were constructed near or even in close proximity to the railway box culverts. In this paper, taking the project of tunnel under railway box culvert in some typical section of Beijing Metro Line as an example, we studied the deformation responses of railway box culverts under the metro shield tunnels by numerical simulation method, and analyzed emphatically the effect of grouting reinforcement and the deformation mechanism of the both sides of settlement joint. The research results show that: (1) When the shield tunnel passes beneath the railway box culvert, the horizontal interval in longitudinal direction effected by the settlement monitoring site covers a distance between 3D (D is shield tunnel diameter) before the site and 3D behind the site;(2) When the shield tunnel passes beneath the railway box culvert, the railway box culverts on both sides of the settlement joint demonstrate large differences in settlement, so it is easy to influence the safety of the trains running above the bridge; (3) Before the shield tunnel passes beneath the railway box culvert, grouting reinforcement of the shield tunnel vault can control the settlement of bridges to some degree and the differential settlement on both sides of the settlement joint.
