To avoid tensile failure of bolts as a result of the superposition effect of stress accumulation, a segmentally yieldable anchorage support, taking into consideration the different failure zones in surrounding rock, is presented in this paper. First, load transfer mechanisms and the process of anchorage failure are analyzed for end anchorage, full-length anchorage, and segmentally yieldable anchorage based on numerical pull-out tests. Results show that the load transfer follows a multipeak chain-like trend in the case of multipoint segmental anchorage, and that the peaks of stress attenuate slowly. Therefore, the proposed anchorage type can leverage the shear strength effectively. Furthermore, numerical models for the applications of the aforementioned three different anchoring modes to weakly consolidated soft strata are established. Results indicate that segmentally yieldable anchorage can withstand larger tensile deformation and surrounding rock deformation. Moreover, the bolt shows higher strength reservation. A combination of these characteristics is conducive to controlling deformation and damage during roadway excavation.<\/jats:p>","DOI":"10.1177\/0037549718770284","type":"journal-article","created":{"date-parts":[[2018,5,14]],"date-time":"2018-05-14T04:36:22Z","timestamp":1526272582000},"page":"83-96","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":21,"title":["Load transfer mechanism and reinforcement effect of segmentally yieldable anchorage in weakly consolidated soft rock"],"prefix":"10.1177","volume":"95","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6335-1655","authenticated-orcid":false,"given":"Zenghui","family":"Zhao","sequence":"first","affiliation":[{"name":"State Key Laboratory of Mining Disaster Prevention and Control Co-founded by Shandong Province and the Ministry of Science and Technology, Shandong University of Science and Technology, Qingdao, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qing","family":"Ma","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mining Disaster Prevention and Control Co-founded by Shandong Province and the Ministry of Science and Technology, Shandong University of Science and Technology, Qingdao, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunliang","family":"Tan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mining Disaster Prevention and Control Co-founded by Shandong Province and the Ministry of Science and Technology, Shandong University of Science and Technology, Qingdao, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaojie","family":"Gao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mining Disaster Prevention and Control Co-founded by Shandong Province and the Ministry of Science and Technology, Shandong University of Science and Technology, Qingdao, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,5,14]]},"reference":[{"key":"bibr1-0037549718770284","doi-asserted-by":"publisher","DOI":"10.1631\/jzus.A1300314"},{"key":"bibr2-0037549718770284","doi-asserted-by":"publisher","DOI":"10.1016\/j.tust.2015.01.007"},{"key":"bibr3-0037549718770284","first-page":"739","volume-title":"Proceedings of the international symposium on engineering in complex rock formations","author":"Cheng L"},{"key":"bibr4-0037549718770284","doi-asserted-by":"publisher","DOI":"10.1007\/s40789-014-0043-0"},{"key":"bibr5-0037549718770284","doi-asserted-by":"publisher","DOI":"10.1007\/s10706-014-9820-1"},{"key":"bibr6-0037549718770284","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcsr.2012.03.021"},{"issue":"4","key":"bibr7-0037549718770284","first-page":"692","volume":"26","author":"Yang Q","year":"2007","journal-title":"Chin J Rock Mech Eng"},{"issue":"2","key":"bibr8-0037549718770284","first-page":"271","volume":"31","author":"Zhang AM","year":"2009","journal-title":"Chin J Geotech Eng"},{"key":"bibr9-0037549718770284","volume-title":"Proceedings of the international conference organised by the Institution of Civil Engineers","author":"Woods RI"},{"issue":"3","key":"bibr10-0037549718770284","first-page":"379","volume":"21","author":"Zhu HC","year":"2002","journal-title":"Chin J Rock Mech Eng"},{"key":"bibr11-0037549718770284","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijmst.2015.11.010"},{"key":"bibr12-0037549718770284","doi-asserted-by":"publisher","DOI":"10.1080\/17486025.2014.933893"},{"key":"bibr13-0037549718770284","doi-asserted-by":"publisher","DOI":"10.1016\/j.compstruct.2016.11.060"},{"key":"bibr14-0037549718770284","unstructured":"YOU CA.
