| Abstract: | 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. |
