Monitoring Analysis on Tunnel Portal Shallow Burying Segment of Center Diaphragm Construction Method
Combined with highway tunnel monitoring measurement work of Bijia Mountain,the contents and methods of site monitoring and the analyzing methods for collected data of highway tunnel construction were studied.A comparative way was used to analyze the different curves of displacement with time on the two typical segments of ground settlement convergence and vault crown settlement.The result shows that the site monitoring curves of displacement with time can be divided into normal type and abnormal one.This article puts forward some feasible suggestions about how to guide the safe construction through the two types of curve.The aim of this article is to explore the changing of the abnormal curve before the dangerous accident occur,and give the causes of the reasonable analysis after collapse happened.
