摘要
以广深港客运专线福田地下车站(建设中)基坑施工为例,重点介绍城市CBD区大型地下车站超深、超厚地下连续墙的设备选型及施工技术特点、方法,大跨度、大截面型钢劲性钢筋混凝土结构柱的关键施工技术以及施工监控所采用的仿真检测和动态监控技术。有效地控制了施工过程中可能引起的周边高层建筑群稳定性畸变,保障了城市CBD区超宽、超深特大型地下空间工程实施的安全需求。
The construction technology and equipment selection for super-deep and super-thick diaphragm wall of large- scale railway station adjacent to CBD building group in urban area are presented. Key construction technologies for large- span and large-cross-section steel reinforced concrete structure column are presented. Simulated monitoring technology and dynamic monitoring technology are used. In the end, the deformation of the surrounding high buildings has been brought under effective control and the safe construction of large-scale structure adjacent to CBD building group in urban area has been guaranteed.
