摘　　要：基于广州地铁18号线北延段白云东平至白云城市中心盾构区间隧道在岩溶发育区穿越市政桥梁,采用有限元软件对Midas GTS/NX对此过程进行数值模拟分析,探讨盾构在岩溶强发育地区中穿越桥梁对附近地层及其桥桩的影响。Based on the shield tunnel crossing the municipal bridge in the karst development area from Dongping Baiyun to Baiyun city center in the north extension of Guangzhou Metro Line 18, the finite element software Midas GTS/NX was used to simulate this process, and the influence of shield tunnel crossing the karst strong development area on the nearby strata and the bridge pile was discussed.

关 键 词：岩溶地区 盾构隧道 数值模拟 桥桩
