To determine the stress arching effect in horizontally layered jointed rock mass, the stress arching characteristics of surrounding rock mass after excavation is analyzed in this study by using a series of numerical tests. The formation mechanism of stress arch is revealed through a comparison of the stress characteristics of a voussoir beam structure and theoretical analysis of multi-block mechanical relationship of jointed rock mass. The method for determining the boundaries of a stress arching zone is proposed, and the influence of various factors on a stress arch is further discussed. Results show that after the excavation of horizontally layered jointed rock mass, the stress arch bunch (SAB) is formed in the lower strata above the cavern, and the global stress arch (GSA) is formed in the higher strata, both of which are symmetrical arch stress patterns. The SAB is the mechanical manifestation of the voussoir beam structure formed by several low-level sandstone layers, and the GSA is caused by the uneven displacement between blocks. Compared with the GSA, the SAB is more sensitive to various influencing factors. The extent of stress arching zone decreases with the increase of an internal friction angle of the joint, lateral pressure coefficient, and overburden depth. In addition, the joint spacing of rock strata is conducive to the development of a stress arch. Results can provide technical support for deformation control and the stability analysis of broken surrounding rock in underground engineering.<\/jats:p>","DOI":"10.3390\/sym13071138","type":"journal-article","created":{"date-parts":[[2021,6,25]],"date-time":"2021-06-25T11:07:40Z","timestamp":1624619260000},"page":"1138","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Numerical Simulation of Stress Arching Effect in Horizontally Layered Jointed Rock Mass"],"prefix":"10.3390","volume":"13","author":[{"given":"Xiao","family":"Huang","sequence":"first","affiliation":[{"name":"Key Laboratory of Ministry of Education for Geomechanics and Embankment Engineering, Hohai University, Nanjing 210024, China"},{"name":"Research Institute of Geotechnical Engineering, Hohai University, Nanjing 210024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huaining","family":"Ruan","sequence":"additional","affiliation":[{"name":"Key Laboratory of Ministry of Education for Geomechanics and Embankment Engineering, Hohai University, Nanjing 210024, China"},{"name":"Research Institute of Geotechnical Engineering, Hohai University, Nanjing 210024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chong","family":"Shi","sequence":"additional","affiliation":[{"name":"Key Laboratory of Ministry of Education for Geomechanics and Embankment Engineering, Hohai University, Nanjing 210024, China"},{"name":"Research Institute of Geotechnical Engineering, Hohai University, Nanjing 210024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Kong","sequence":"additional","affiliation":[{"name":"Department of Geotechnical Engineering, Nanjing Hydraulic Research Institute, Nanjing 210029, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"16","DOI":"10.1016\/j.enggeo.2012.02.007","article-title":"Deformation mechanisms and stability analysis of undermined sedimentary rocks in the shallow subsurface","volume":"133","author":"Tsesarsky","year":"2012","journal-title":"Eng.
