Abstract

Abstract:

The 9.34 m diameter EPB shield machines are used for boring of Bingjiangxincheng StationKaifusi Station section of ChangshaZhuzhouXiangtan railway. The active protection of buildings on the ground and optimization of construction program and parameters are used, so as to control the settlement and deformation of buildings. In the end, the shield machines have successfully passed through, the settlement of ground surface has been brought under effective control, and the safety of the buildings on the ground has been guaranteed.

Key words: EPB shield machien, large crosssection, boring underneath buildings, settlement control
