Combined with data collected by acoustic emission instruments, the mechanical characteristics of fracture and failure, crack propagation mechanism, and acoustic emission response mechanism of fissured rock masses under the coupling effect of stable hydraulic pressure and stress were studied. The results showed that throughout the entire experimental process, the hydraulic pressure remained continuously stable, with a decrease of only 0.14%; The variation pattern of peak strength of fissured rock mass with increasing crack inclination angle under stable hydraulic pressure changes from a decrease and then an increase in the absence of hydraulic pressure to an increasing trend; The crack propagation length of low angle fissured rock mass is generally higher than that of high angle fissured specimens. The longer propagation path increases the range and effect of hydraulic pressure, and the initial crack propagation length of fissured rock mass under hydraulic pressure is also significantly longer than that of specimens without hydraulic pressure; During the loading process, both the acoustic emission ringing count and damage variable can be divided into four stages. From the cumulative total number of acoustic emission ringing counts, it can be seen that during the loading process, the total number of acoustic emission ringing in fissured rock masses subjected to hydraulic pressure is significantly lower than that of specimens without hydraulic pressure, and the trend is also relatively stable.<\/jats:p>","DOI":"10.1371\/journal.pone.0307700","type":"journal-article","created":{"date-parts":[[2024,9,20]],"date-time":"2024-09-20T13:33:11Z","timestamp":1726839191000},"page":"e0307700","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":3,"title":["Tunnel and underground engineering rock mass water inrush damage and acoustic emission characteristics"],"prefix":"10.1371","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0127-3548","authenticated-orcid":true,"given":"Jiajun","family":"Zeng","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengzhi","family":"Pu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiyun","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingqing","family":"Shen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiang","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhicheng","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2024,9,20]]},"reference":[{"key":"pone.0307700.ref001","doi-asserted-by":"crossref","first-page":"105247","DOI":"10.1016\/j.compgeo.2023.105247","article-title":"Coupled hydro-mechanical analysis for water inrush of fractured rock masses using the discontinuous deformation analysis.","volume":"156","author":"Gao Jingyao","year":"2023","journal-title":"Computers and Geotechnics"},{"issue":"1","key":"pone.0307700.ref002","article-title":"A state-of-the-art review on rock seepage mechanism of water inrush disaster in coal mines","volume":"9","author":"Ma Dan","year":"2022","journal-title":"International Journal of Coal Science Technology"},{"issue":"8","key":"pone.0307700.ref003","doi-asserted-by":"crossref","first-page":"5163","DOI":"10.1007\/s00603-022-02878-9","article-title":"Numerical Simulation of Water-Silt Inrush Hazard of Fault Rock: A Three-Phase Flow Model[J].","volume":"55","author":"Ma Dan","year":"2022","journal-title":"Rock Mechanics and Rock Engineering"},{"key":"pone.0307700.ref004","first-page":"126","article-title":"Solid grain migration on hydraulic properties of fault rocks in underground mining tunnel: Radial seepage experiments and verification of permeability prediction[J].","author":"Ma Dan","year":"2022","journal-title":"Tunnelling and underground space technology"},{"issue":"1","key":"pone.0307700.ref005","doi-asserted-by":"crossref","first-page":"66","DOI":"10.1007\/s40948-024-00774-w","article-title":"Case study on the secondary support time and optimization of combined support for a roadway under high in-situ stress.","volume":"10","author":"Geng Weile","year":"2024","journal-title":"Geomech.
