Based on the geological conditions and structural dimensions of the Taiyuan Yingze Street Underpass Project, by analogy to the structural sections of Shenyang Metro Xinle Ruins Station and Seoul Metro Lot 923 Station, three research cases were designed: \u201cTaiyuan method\u201d, \u201cShenyang method\u201d and \u201cSeoul method\u201d. The numerical models are established, and the construction process of three cases are simulated. The results show that the three forms of the New Tubular Roof Method have different characteristics. The impact of construction on the rail is mainly reflected in the absolute settlement, while the offset of the rail and the relative displacement between the rails are small, which are not enough to pose a threat to the driving safety. \u201cTaiyuan method\u201d has the best control effect on the deformation of the rails in general, but there is a complex superimposed interference effect during tube jacking, and the settlement in the tube jacking stage accounts for a large proportion. \u201cTaiyuan method\u201d and \u201cShenyang method\u201d adopt the integrated inner-connecting tube roof structure to cover the entire excavation area, which have excellent effect of isolating excavation disturbance. However, \u201cShenyang method\u201d has the problem of excessive settlement during the stage of steel tube incision. The settlement caused by the construction of \u201cSeoul method\u201d in the tube jacking stage is relatively small, and there is no need to perform the complicated and dangerous tube incision. However, the excavation disturbance of \u201cSeoul method\u201d will partially escape from the side of the structure, and the excavation influence range is significantly larger than other methods.<\/jats:p>","DOI":"10.3390\/sym14071361","type":"journal-article","created":{"date-parts":[[2022,7,4]],"date-time":"2022-07-04T23:38:55Z","timestamp":1656977935000},"page":"1361","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Comparative Study on the Influence of Different Forms of New Tubular Roof Method Construction on Railway Tracks"],"prefix":"10.3390","volume":"14","author":[{"given":"Xiaoxue","family":"Li","sequence":"first","affiliation":[{"name":"Key Laboratory of Urban Underground Engineering of Ministry of Education, Beijing Jiaotong University, Beijing 100044, China"},{"name":"POWERCHINA Hebei Electric Power Engineering Co., Ltd., Shijiazhuang 050000, China"}]},{"given":"Zhongsheng","family":"Tan","sequence":"additional","affiliation":[{"name":"Key Laboratory of Urban Underground Engineering of Ministry of Education, Beijing Jiaotong University, Beijing 100044, China"}]},{"given":"Xiuying","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Urban Underground Engineering of Ministry of Education, Beijing Jiaotong University, Beijing 100044, China"}]},{"given":"Ke","family":"Lei","sequence":"additional","affiliation":[{"name":"Key Laboratory of Urban Underground Engineering of Ministry of Education, Beijing Jiaotong University, Beijing 100044, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"241","DOI":"10.1016\/j.tust.2016.02.013","article-title":"Tunnelling undercrossing existing live MRT tunnels","volume":"57","author":"Sze","year":"2016","journal-title":"Tunn.
