摘要
为进一步完善类矩形盾构法隧道的施工保护技术,以宁波轨道交通4号线类矩形盾构区间为工程背景,开展了建筑物保护施工配合研究。经工程实践检验证明,类矩形盾构法隧道施工技术在沿途近距离侧穿老旧建筑的情况下,对周边的地层环境有较好的保护效果,验证了类矩形盾构法隧道工法在城市核心区、老旧城区地下空间诸多限制条件下修建隧道的优越性。
To further improve the construction protection technology of quasi-rectangular shield tunnel,taking the similar rectangular shield section of Ningbo Rail Transit Line 4 as the engineering background,the cooperated research on building protection construction was carried out.The engineering practice test proved that the quasi-rectangular shield tunnel construction technology has a good protection effect on the surrounding stratum environment when passing through the old buildings in a short distance along the way,which verifies that the quasi-rectangular shield tunneling method has advantages in tunnel construction in urban core area and old urban districts with many restricted underground space conditions.
