Shield Cable Tunnel Settlement Subsidence Regulation and Prediction Based on Measured Data
-
Abstract
Shield cable tunnel settlement subsidence regulations are analysed based on measured data. The reasons for differences of measured data and experience data are analysed after comparing the measured data with experience formulas, the correction methods of settlement prediction are provided. First, the subsidence and the law of its development caused by shield construction are analysed. Secondly, the experience formulas for subsidence prediction are given, the reasons for differences of measured data and experience data are obtained according to the characteristics of the actual project. Finally, the correction methods of settlement prediction are obtained. The results show that the shield construction status and the settlement prediction parameters could be obtained through analysing measured data, which could provide technical guidance to the shield construction, they could also provide references to the similar construction.
