摘要
结合西安地铁四号线盾构隧道两次下穿和平门外护城河拱桥工程,利用有限元软件建立了三维模型,计算研究了地层、拱桥沉降及受力情况,制定了拱桥加固措施和保护方案,提出了拱桥保护的沉降控制标准,并分析了实际施工过程中沉降监测数据,验证了拱桥沉降控制标准的合理性。
Combining with Xi’an subway line 4 shield tunnel twice passing through Hepingmen moat arch bridge engineering,using the finite element software established the three-dimensional model,calculated and analyzed the settlement,arch bridge subsidence and force situation,formulated the arch bridge reinforcement measures and protection scheme,put forward the settlement control standards of arch bridge protection,and analyzed the subsidence monitoring data in actual construction process,verified the rationality of arch bridge subsidence control standard.
