摘要
结合杭州某电缆隧道送出工程的地质情况以及顶管的施工工艺,采用有限元分析,综合分析了引起路面沉降、邻近建筑物位移变形的情况。顶管施工引起的地面位移变形在10~27 mm之间,且主要影响范围在掘进法向2.5D处(D为顶管直径);周边建筑物影响较小,最大不均匀沉降为0.4 mm,影响相对可控。
Combined with the geological conditions of a cable tunnel delivery project in Hangzhou and the construction technology of pipe jacking,the finite element analysis is used to comprehensively analyze the conditions that cause road surface settlement and adjacent building displacement and deformation.The ground displacement and deformation caused by pipe jacking construction is between 10 and 27 mm,and the main impact range is at the 2.5D normal direction of the excavation.The impact of surrounding buildings is small,and the maximum uneven settlement is 0.4 mm,and the impact is relatively controllable.
