Due to the effect of blasting impact, hole collapse can easily occur in the hole-forming stage of pile foundation construction. In order to prevent hole collapse, it is very necessary to evaluate the stability of a pile hole wall before pile foundation construction. The calculation of hole collapse can usually be attributed to an axisymmetric circular hole stress concentration problem. However, the existing collapse failure theory of pile hole hardly considers the effect of blasting impact load. In view of this, this paper proposes the stability evaluation method of a pile hole wall under blasting impact. Compared with the existing collapse failure theory, the proposed method fully considers the effect of blasting impact stress. Using Mohr\u2013Coulomb strength theory and symmetry analysis, the strength condition of collapse failure is established in this work for accurate evaluation of the stability of a hole wall. The proposed stability evaluation method is demonstrated by a pile foundation construction project of a bridge. Moreover, a shaking table test on the pile hole model was performed to verify the proposed method by experimental data. The results indicate the effectiveness and usability of the proposed method. The proposed method provides a feasible way for the stability analysis of a pile hole wall under blasting impact.<\/jats:p>","DOI":"10.3390\/sym14010079","type":"journal-article","created":{"date-parts":[[2022,1,9]],"date-time":"2022-01-09T23:35:09Z","timestamp":1641771309000},"page":"79","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Stability Evaluation Method of Hole Wall for Bored Pile under Blasting Impact"],"prefix":"10.3390","volume":"14","author":[{"given":"Qiuwei","family":"Yang","sequence":"first","affiliation":[{"name":"School of Civil and Transportation Engineering, Ningbo University of Technology, Ningbo 315211, China"},{"name":"Engineering Research Center of Industrial Construction in Civil Engineering of Zhejiang, Ningbo University of Technology, Ningbo 315211, China"}]},{"given":"Zhikun","family":"Ba","sequence":"additional","affiliation":[{"name":"School of Civil and Transportation Engineering, Ningbo University of Technology, Ningbo 315211, China"},{"name":"Engineering Research Center of Industrial Construction in Civil Engineering of Zhejiang, Ningbo University of Technology, Ningbo 315211, China"}]},{"given":"Zhuo","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Civil and Transportation Engineering, Ningbo University of Technology, Ningbo 315211, China"},{"name":"Engineering Research Center of Industrial Construction in Civil Engineering of Zhejiang, Ningbo University of Technology, Ningbo 315211, China"}]},{"given":"Xi","family":"Peng","sequence":"additional","affiliation":[{"name":"School of Civil and Transportation Engineering, Ningbo University of Technology, Ningbo 315211, China"},{"name":"Engineering Research Center of Industrial Construction in Civil Engineering of Zhejiang, Ningbo University of Technology, Ningbo 315211, China"}]},{"given":"Yun","family":"Sun","sequence":"additional","affiliation":[{"name":"School of Civil and Transportation Engineering, Ningbo University of Technology, Ningbo 315211, China"},{"name":"Engineering Research Center of Industrial Construction in Civil Engineering of Zhejiang, Ningbo University of Technology, Ningbo 315211, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2067","DOI":"10.1007\/s12517-021-08459-4","article-title":"Study on the value of side friction of bored pile in loess area considering the influence of length diameter ratio","volume":"14","author":"Tian","year":"2021","journal-title":"Arab.
