摘要
以南昌轨道交通1号线区间隧道盾构施工为工程背景,采用Mohr-Coulomb建立模型,研究分析不同工况下富水砂层盾构下穿浅基础桥梁的变形规律及施工风险,根据现场及风险评估结果提出盾构下穿浅基础桥梁施工时的控制措施,并制定了监测方案。
Taking the construction of segmental tunnel of Nanchang Railway Traffic No. 1 Line as a background,the model of Mohr-Coulomb is applied,and the deformation rules and construction risk of watered sandy stratum when the shield jacking the foundation bridge at different conditions is analyzed. The construction control measures on the shield jacking the foundation bridge are put forward including the field and risk estimated solution,then monitoring scheme is planned.
