Based on the theory of discontinuous medium, the uniaxial compression and uniaxial tensile tests of rocks were simulated, and the microscopic mechanical parameters of discrete elements of granite samples were determined based on the indoor macroscopic mechanical tests: effective modulus Et, compressive elastic modulus Ec, macro Poisson\u2019s ratio \u03bc, and uniaxial compressive strength \u03c3c. The results show that the parallel bond model has good simulation results for the uniaxial compression test, but the tensile strength and tensile\u2013compression ratio were quite different from the experimental values. When the confining pressure is large, the calibrated parameter adaptability by uniaxial compression is poor. The reason for certain errors is a large resistance of the parallel bond model to particle rotation and the influence of normal stress on shear strength is not considered. The cementation model can be modified by adding coefficients based on laboratory test results.<\/jats:p>","DOI":"10.3390\/ma15113878","type":"journal-article","created":{"date-parts":[[2022,5,29]],"date-time":"2022-05-29T08:50:51Z","timestamp":1653814251000},"page":"3878","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Study on Meso-Material Parameters of Submarine Weathered Granite Based on Parallel Bond Model"],"prefix":"10.3390","volume":"15","author":[{"given":"Shilei","family":"Zhang","sequence":"first","affiliation":[{"name":"Inner Mongolia Yinchuo Jiliao Water Supply Co., Ltd., Hinggan 137400, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0287-0355","authenticated-orcid":false,"given":"Bonan","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Shandong University, Jinan 250061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Han","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Shandong University, Jinan 250061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiyue","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Shandong University, Jinan 250061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Di","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Shandong University, Jinan 250061, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"109809","DOI":"10.1016\/j.oceaneng.2021.109809","article-title":"Influence of soil scour on lateral behavior of large-diameter offshore wind-turbine monopile and corresponding scour monitoring method","volume":"239","author":"Dai","year":"2021","journal-title":"Ocean Eng."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"5013","DOI":"10.1016\/j.rser.2011.07.053","article-title":"Development of offshore wind power in China","volume":"15","author":"Chen","year":"2011","journal-title":"Renew.
