The results show that with a series of monitoring to all the intemal and extemal factors that influence the subway structure , the influences of nearly underground renovation construction to suhway structures such as deformations or subsidence were successfully avoided. The structural safety as well as the normal operation of the subway lines was guaranteed during the renovation construction.
