Abstract

In recent years,it is normal that tunnels under construction cross closely above existing Metro structure in urban areas. As a result,studies on the control of the deformation of the existing structure become a hot topic. In the construction of the shield-bored tunnel of Chegongmiao station-Hongshuwan station section on No. 11 line of Shenzhen Metro,which crosses closely above the existing Zhuzilin station-Qiaochengdong station of No. 1 line of Shenzhen Metro, technologies,such as reinforcement of ground above the existing Metro line,shield boring control technology and existing structure monitoring technology,are used. In the end,the deformation of the existing structure has been brought under effective control,and the safety of the shield-bored tunnel and the operation of the existing Metro line have been guaranteed.
