STUDY ON MUCK REPLACEMENT RATE OF TRD CONSTRUCTION FOR END REINFORCEMENT OF SUBWAY SHIELD TUNNELING
Linjiang rich water powder fine sand formation large diameter shield starting and receiving well end reinforcement effect has high requirements,TRD canal cutting cement as a stratum reinforcement measures,has good reinforcement effect,this paper through the TRD channel cutting cement reinforcement method combined with subway large diameter shield interval end reinforcement engineering example,introduces the TRD channel cutting cement wall construction technology and parameter control.The main factors affecting the replacement rate of the replacement soil are analyzed,and the theoretical replacement rate is calculated through the theoretical formula.Compared with the actual site replacement volume,the theoretical results of TRD method are obtained,which provides reference experience for the subsequent engineering construction organization.
