The study of shear deformation and the failure of rock structural planes plays a vital role in ensuring the safety and stability of engineered rock masses. In view of the inability of traditional shear constitutive models to describe the non-linear characteristics of the dilatancy stage and the single applicable failure form, firstly, we discuss, in depth, the law and mechanism of shear deformation and failure of structural planes, and introduce the compaction index \u03b1 to measure the non-linear characteristics of shear stress\u2013shear displacement caused by compaction of microcracks and internal pores of structural planes, and the structural plane damage model, considering the void compaction and failure mode, was established. Then, the statistical damage theory was introduced, and the strength and failure of the microunits of the rock structural plane were assumed to obey the Weibull distribution. Based on the Mohr-Coulomb strength criterion to measure the strength of the microunits of the rock structure surface, a statistical damage model of structural planes, which can describe void compaction and failure modes, was established. Finally, a comparative analysis was carried out with the test curve, and the results showed that: the calculation curve of the structural plane statistical damage model established, considering the void compaction and failure modes, has the same trend as the structural plane shear test curve, which can better describe the shear stress\u2013 shear displacement at the dilatancy stage, as well as the shearing stage and sliding stage in different failure modes. The changing law of shear displacement reflects the rationality and accuracy of the constructed constitutive model. The research results can provide a theoretical basis for the shear deformation and failure of rock structural planes.<\/jats:p>","DOI":"10.3390\/sym14030434","type":"journal-article","created":{"date-parts":[[2022,2,22]],"date-time":"2022-02-22T22:35:00Z","timestamp":1645569300000},"page":"434","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Statistical Damage Model of Rock Structural Plane Considering Void Compaction and Failure Modes"],"prefix":"10.3390","volume":"14","author":[{"given":"Bin","family":"Hu","sequence":"first","affiliation":[{"name":"School of Resources and Environmental Engineering, Wuhan University of Science and Technology, Wuhan 430081, China"},{"name":"Hubei Key Laboratory for Efficient Utilization and Agglomeration of Metallurgic Mineral Resources, Wuhan 430081, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7997-0055","authenticated-orcid":false,"given":"Zhen","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Resources and Environmental Engineering, Wuhan University of Science and Technology, Wuhan 430081, China"},{"name":"Hubei Key Laboratory for Efficient Utilization and Agglomeration of Metallurgic Mineral Resources, Wuhan 430081, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7802-772X","authenticated-orcid":false,"given":"Jing","family":"Li","sequence":"additional","affiliation":[{"name":"School of Resources and Environmental Engineering, Wuhan University of Science and Technology, Wuhan 430081, China"},{"name":"Hubei Key Laboratory for Efficient Utilization and Agglomeration of Metallurgic Mineral Resources, Wuhan 430081, China"}]},{"given":"Huiping","family":"Xiao","sequence":"additional","affiliation":[{"name":"Huangshi Construction Market Management Station, Huangshi 435000, China"}]},{"given":"Zeqi","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Resources and Environmental Engineering, Wuhan University of Science and Technology, Wuhan 430081, China"},{"name":"Hubei Key Laboratory for Efficient Utilization and Agglomeration of Metallurgic Mineral Resources, Wuhan 430081, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,22]]},"reference":[{"key":"ref_1","unstructured":"Cai, M., He, M., and Liu, D.
