In this study, a method for estimating the subsidence of soil layer at any depth is firstly proposed based on the total self-weight collapse value. Secondly, a new load transfer constitutive model for pile-soil interface is developed, which considers the nonlinear stress-strain relationship and the ultimate shear strength of soil. Then, a load transfer calculation model for pile foundation is established, which can calculate the pile axial force, the pile skin frictional, neutral point position and the settlement of a single pile. The calculation results are compared with the test data that obtained from a pile foundation on-site immersion test and the effectiveness of the calculation method is verified well. This calculation method may be useful for designing pile foundations in collapsible loess regions.<\/jats:p>","DOI":"10.1371\/journal.pone.0290878","type":"journal-article","created":{"date-parts":[[2023,8,31]],"date-time":"2023-08-31T17:38:37Z","timestamp":1693503517000},"page":"e0290878","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":7,"title":["Research on the bearing behavior of single pile in self-weight collapsible loess areas"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7525-8677","authenticated-orcid":true,"given":"Denghui","family":"Gao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kuanyao","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Baohong","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiping","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jifei","family":"Fan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,8,31]]},"reference":[{"issue":"6","key":"pone.0290878.ref001","doi-asserted-by":"crossref","first-page":"1476","DOI":"10.1016\/j.sandf.2018.08.005","article-title":"Experimental study on settling characteristics of thick self-weight collapsible loess in Xinjiang Ili region in China using field immersion test.","volume":"58","author":"P An","year":"2018","journal-title":"Soils and Foundations"},{"issue":"3","key":"pone.0290878.ref002","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1139\/t92-044","article-title":"Development of negative skin friction on driven piles in soft Bangkok clay","volume":"29","author":"B Indraratna","year":"1992","journal-title":"Canadian Geotechnical Journal"},{"issue":"12","key":"pone.0290878.ref003","doi-asserted-by":"crossref","first-page":"2030","DOI":"10.1139\/cgj-2015-0548","article-title":"Drag load on end-bearing piles in collapsible soil due to inundation","volume":"53","author":"I Mashhour","year":"2016","journal-title":"Canadian Geotechnical Journal"},{"key":"pone.0290878.ref004","doi-asserted-by":"crossref","first-page":"94","DOI":"10.1016\/j.catena.2013.07.006","article-title":"Loessification and hydroconsolidation: There is a connection.","volume":"117","author":"IJ Smalley","year":"2014","journal-title":"Catena"},{"issue":"1","key":"pone.0290878.ref005","doi-asserted-by":"crossref","first-page":"249","DOI":"10.1016\/j.enggeo.2014.07.021","article-title":"Peng, JB.
