In this paper, a case of jacked box tunnels built closely over-crossing the existing subway tunnels in Suzhou, China, is presented. The tunneling-induced deformation of the subway tunnels is measured and analyzed. The measurement indicates that the subway tunnels are uplifted and subjected to the overcrossing box tunneling. As compared, the longitudinal deformation of the range that locates under the box tunnels is more significant than that outside the range. The tunneling-induced deformation of the left subway tunnel is relatively higher than that of the right one. The numerical simulation is performed for validation. The numerical result is agreed with the in-situ measurements. Moreover, the simulation reveals that the presence of friction in jacked tunnels causes the extra uplift deformation of subway tunnels. The higher the friction, the is the deformation. It is affirmed that using the effective lubrication not only facilitates the tunnel jacking but also inabilities the tunneling-induced deformation of underlying tunnels<\/jats:p>","DOI":"10.3390\/sym13101800","type":"journal-article","created":{"date-parts":[[2021,9,27]],"date-time":"2021-09-27T23:08:31Z","timestamp":1632784111000},"page":"1800","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Deformations of Subway Tunnels Induced by the Overcrossing Jacked Box Tunnels"],"prefix":"10.3390","volume":"13","author":[{"given":"Wei","family":"Liu","sequence":"first","affiliation":[{"name":"School of Rail Transportation, Soochow University, Suzhou 215000, China"}]},{"given":"Yinlong","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Rail Transportation, Soochow University, Suzhou 215000, China"}]},{"given":"Huajing","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Rail Transportation, Soochow University, Suzhou 215000, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9713-0535","authenticated-orcid":false,"given":"Xiangyang","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Rail Transportation, Soochow University, Suzhou 215000, China"}]},{"given":"Lingyi","family":"Miao","sequence":"additional","affiliation":[{"name":"School of Rail Transportation, Soochow University, Suzhou 215000, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"103614","DOI":"10.1016\/j.tust.2020.103614","article-title":"Twin tunnelling induced ground settlements: A review","volume":"110","author":"Islam","year":"2021","journal-title":"Tunn.
