On the basis of massive searching of foreign and domestic literatures combined with practical experience on spot, both advantages and disadvantages of the monitoring technology on peripheral displacement of the tunnel have been analyzed, as well as the virtues and shortcomings of the treatments of monitoring data. In this work, a novel monitoring technology on peripheral displacement of the tunnel based on strain has been proposed and the wavelet anti-noise analytical method is employed to deal with the monitoring data. Theoretical derivation and computational method are presented and numerical simulation has been done to verify this computational model. The influence of installing span, rigidity and maximal deformation of the monitoring plate on the accuracy of the theoretical calculation is suggested. Meanwhile, in the indoor experiments, there are some requirements of the measuring accuracy of the strain gauge put forward. In the research of the treatment of monitoring data, the wavelet anti-noise analytical method could efficiently eliminate the fluctuation originating from random error while retaining the information of varying displacement affected by construction and ambient environment |
