| 摘 要： | 因地基承载力不足或支持不对称等因素引起主体结构不均匀沉降等结构病害是砖石结构古建筑保护的核心工作之一.采用手掘式顶管技术缓慢均匀地顶入预制的空心箱梁,随后浇筑芯梁,使之形成整体,从而使建筑物逐步的坐落在一个具有足够刚度的"托盘"之上,从而彻底地解决因地基承载力不足或支持不对称引起的结构病害.在介绍手掘式顶管技术在砖石结...

| Abstract: | The structural damages,which result from the inadequate bearing capacity or the asymmetric support of foundation,are one of the crucial works in the conservation of historical masonry constructions.Firstly,the box girders are slowly and evenly jacked by the manual pipe jacking technique,and then casting the core beam to form a whole,so the construction is gradually situated on a "tray"with sufficient rigidity.Consequently,the structural damages caused by the inadequate bearing capacity or the asymmetric support of foundation are thoroughly treated.According to a practical engineering,the principle of the underpinning by manual pipe-jacking,the design of the box-section beam,the techniques of jacking are investigated in detail,and some suggestions and specific implementation measures are presented. |
