摘要
基于顶管施工地面沉降的经验预测模型,对顶管施工所引起的沉降槽进行了分析,结合建筑地基基础所允许的变形值,对顶管施工穿越建筑物的安全性问题进行了研究,推导分析了位于顶管上部及周边建筑物安全与否的计算公式。
Based upon empirical anticipating model of ground subsidence in pipe jacking construction ground subsidence caused by pipe jacking construction is analyzed.Combined with allowable deformation value of building foundation safety questions of surrounding buildings in pipe jacking construction are studied.Corresponding formula is derived for safety calculation of bulidngs.
