盾构隧道施工对临近市政桥梁影响的数值分析

Numerical Analysis of Influence of Shield Tunnel Construction on Adjacent Municipal Bridges

城市交通网络的完善使得盾构隧道施工面临更复杂的施工环境,受到工艺的影响,盾构隧道施工会给附近建筑、设施基础稳定性造成一定干扰。为此,文章以市政桥梁为研究对象,分析盾构隧道施工对临近市政桥梁影响的数值。结合具体施工案例,研究构隧道施工对临近市政桥梁的影响程度,并依照分析结果,给出降低施工干扰的防护措施。保护桥梁设施,确保盾构隧道施工顺利进行。

The improvement of urban transportation network makes shield tunnel construction face more complicated construction environment,which is affected by the process.Shield tunnel construction will cause certain disturbance to the stability of nearby buildings and facilities.To this end,the article takes the municipal bridge as the research object,and analyzes the value of shield tunnel construction on the impact of adjacent municipal bridges.Combined with the specific construction case,the degree of influence of the tunnel construction on the adjacent municipal bridge is studied,and according to the analysis results,the protective measures to reduce the construction interference are given.Protect the bridge facilities and ensure the smooth construction of the shield tunnel.
