摘要
为确保盾构隧道施工过程中周边建筑物的安全,文中以合肥市某轨道交通区间为背景,对盾构掘进过程中引起的建筑物沉降进行现场监测,并结合盾构掘进参数,研究盾构隧道掘进施工对不同基础类型建筑物的沉降影响规律。结果表明盾构开挖对桩基础建筑物沉降的影响较大,对独立基础建筑物沉降的影响较小,而对建筑物不均匀沉降的影响刚好相反。
To ensure the safety of surrounding buildings during shield tunnel construction.A certain section of Hefei Rail Transit is taken to study the safety of surrounding buildings during shield tunnel construction,in which on-site monitoring of building settlement caused by shield tunneling is simulated by combining shield tunneling parameters to study the impact of shield tunnel excavation on the settlement of different foundation types of buildings.The results show that shield tunneling has a greater impact on the settlement of pile foundation buildings,a smaller impact on the settlement of independent foundation buildings,and the opposite effect on uneven settlement of buildings.
