During construction, the confining pressure which has a crucial impact on tunnel construction changes due to the variation of groundwater level and applied load. Therefore, the safety of tunnels must have the magnitude of confining pressure accurately estimated. In this study, a complete tunnel confining pressure time axis was obtained through high-frequency field monitoring, the data are segmented into a training set and a testing set. Using GRU and RNN models, a confining pressure prediction model was established, and the prediction results were analyzed. The results indicate that the GRU model has a fast-training speed and higher accuracy. On the other hand, the training speed of the RNN model is slow, with lower accuracy. The dynamic characteristics of soil pressure during tunnel construction require accurate prediction models to maintain the safety of the tunnel. The comparison between GRU and RNN models not only highlights the advantages of the GRU model but also emphasizes the necessity of balancing speed accuracy in tunnel construction confining pressure prediction modeling. This study is helpful in improving the understanding of soil pressure dynamics and developing effective prediction tools to promote safer and more reliable tunnel construction practices.<\/jats:p>","DOI":"10.3390\/s24030866","type":"journal-article","created":{"date-parts":[[2024,1,30]],"date-time":"2024-01-30T12:06:58Z","timestamp":1706616418000},"page":"866","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Confining Pressure Forecasting of Shield Tunnel Lining Based on GRU Model and RNN Model"],"prefix":"10.3390","volume":"24","author":[{"given":"Min","family":"Wang","sequence":"first","affiliation":[{"name":"Polytechnic Institute, Zhejiang University, Hangzhou 310058, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0012-5842","authenticated-orcid":false,"given":"Xiao-Wei","family":"Ye","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Zhejiang University, Hangzhou 310058, China"}]},{"given":"Jin-Dian","family":"Jia","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Zhejiang University, Hangzhou 310058, China"}]},{"given":"Xin-Hong","family":"Ying","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Zhejiang University, Hangzhou 310058, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1298-1710","authenticated-orcid":false,"given":"Yang","family":"Ding","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Hangzhou City University, Hangzhou 310015, China"}]},{"given":"Di","family":"Zhang","sequence":"additional","affiliation":[{"name":"China Railway Siyuan Survey and Design Group Co., Ltd., Wuhan 430063, China"}]},{"given":"Feng","family":"Sun","sequence":"additional","affiliation":[{"name":"China Railway Siyuan Survey and Design Group Co., Ltd., Wuhan 430063, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Xu, T.Y., Wang, M.N., Yu, L., Lv, C., Dong, Y.C., and Tian, Y.
