摘　　要：随着大量大型基坑工程的涌现,地下连续墙结构需要向超深的方向发展,然而现行施工规范尚无较为适合超深地下连续墙的施工方法,特别是接头施工常出现混凝土绕流的现象,另外地下连续墙接头处理技术的发展也明显滞后于挖掘技术的提高,这些都制约着地连墙向超深方向的发展。为此,本文提出了地连墙刚性接头软连接施工关键技术,该技术在处理地下连续墙接头渗、漏水方面效果显著。With the emergence of a large number of large-sized foundation pit projects,the concrete diaphragm wall structure needs to extend to ultra-deep layer.However,current construction specifications have not covered any suitable construction method for ultra-deep concrete diaphragm wall,especially concrete flowing around the joints.In addition,the advancement of joint treatment technique of concrete diaphragm wall obviously lags behind the development of excavation technique.The above shackle a tendency of concrete diaphragm wall to extend to ultra-deep layer.Therefore,a key technology is put forward,which supports the soft connection of rigid joints of concrete diaphragm wall,has a remarkable effect on the improvement of joints to resist water leakage or seepage.
