Abstract

In this paper, the typical working conditions during the excavation of the pit were selected as the background of the Jinan Yellow River tunnel project on the north bank, and the influence of the excavation process on the enclosure structure and soil deformation was analyzed with the help of MADIS GTS/NX finite element analysis software. Based on the analysis of the measured data on site, the measured results are compared with the numerical simulation, and some conclusions that can be used to guide the design and construction are obtained. The results show that the trends of the measured and simulated results are basically the same, and this study can provide reference for similar workhole excavation projects.
