摘　　要：以钱江通道过江隧道工程为背景,利用有限元方法对盾构隧道施工引起的地表变形进行数值模拟分析,与经验公式计算结果比较,验证了有限元数值分析模型的合理性,同时分析了隧道周围土体移动规律和地表沉降规律。Based on the channel tunnel project in Qiantang River, finite element analysis applied to simulate the ground surface settlement caused by shidd tunneling construction. The results are satisfied compared with the outcome of the empirical formula calculation. The laws of soil displacement and ground surface settlement are obtained and the rationality of simulation results confirmed.
