Although heat-treated high-strength rebar has been successfully applied in many fields of civil engineering, its application in tunnel engineering is just getting started. In this study, the on-site test of axisymmetric heat-treated high-strength lattice girders in rail tunnels and road tunnels was carried out. Comparative analysis of the performance of axisymmetric heat-treated high-strength lattice girders and original-design I20b steel rib was conducted. The test results show that the settlement of high-strength lattice girders is decreased by about 7%~30% compared with the test section of original-design I20b steel rib. The surrounding rock pressure is similar, but the stress of high-strength lattice girders is slightly higher than that of I20b steel rib. Due to the better binding ability of the lattice girders and the concrete, the ultimate bearing capacity of the \u2018lattice girders and shotcrete\u2019 is greater than that of the \u2018I20b steel rib and shotcrete\u2019. Moreover, the steel consumption of lattice girder is about 36% less than I20b steel rib, which shows significant economic and social benefits.<\/jats:p>","DOI":"10.3390\/sym11081007","type":"journal-article","created":{"date-parts":[[2019,8,5]],"date-time":"2019-08-05T11:17:47Z","timestamp":1565003867000},"page":"1007","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Experimental Study on the Application of Heat-Treated High-Strength Lattice Girder in Tunnel Engineering"],"prefix":"10.3390","volume":"11","author":[{"given":"Zhongsheng","family":"Tan","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Beijing Jiaotong University, Beijing 100044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5623-6376","authenticated-orcid":false,"given":"Kaihang","family":"Han","sequence":"additional","affiliation":[{"name":"College of Civil and Transportation Engineering, Shenzhen University, Shenzhen 518060, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,5]]},"reference":[{"key":"ref_1","first-page":"6","article-title":"Chinese architecture will enter into the era of high-strength rebar","volume":"19","author":"Wang","year":"2011","journal-title":"Constr.
