Abstract：
At present, earth pressure balanced shield machine is extensively used in urban subway tunnel construction. Although shield machine is advantageous for stratum displacement control in construction, it is still faces great construction risks and land subsidence and collapse accidents often happen due to geological and hydrological influence, as well as restriction of surrounding environment. This paper discussed the reasons for ground collapse caused by earth pressure balanced shield construction to find out the earth pressure management method and analyzed ground collapse accident in typical earth pressure balanced shield machine construction to propose measures for reducing and avoiding accident.
