摘要
In this paper, through embedding steel bar meters at some key positions such as vault, spandrel and hence in primary support and secondary lining of tunnel, systematical study is carried out on reinforcement stress variations during 3 tunneling phases such as upper bench excavation, lower bench excavation and secondary lining construction. The drawn conclusions from the study of this paper could be taken as references for tunnel lining structure design in III similar to IV grade of surrounding rock.(1)
