Uncertainty information not only affects the accuracy of evaluation results, but also affects the reliability of decision-making schemes. Therefore, it is necessary to evaluate and control the impact of uncertainty on risk. In this study, the problems in the existing entropy-hazard model such as inefficient decision-making and failure of decision-making are analysed, and an improved uncertainty evaluation and control process are proposed. Then the tolerance cost, the key factor in the decision-making model, is also discussed. It is considered that the amount of change in risk value (R1) can better reflect the psychological behaviour of decision-makers. Thirdly, common multi-attribute decision-making models, such as the expected utility-entropy model, are analysed, and then the viewpoint of different types of decision-making issues that require different decision methods is proposed. The well-known Allais paradox is explained by the proposed methods. Finally, the engineering application results show that the uncertainty control idea proposed here is accurate and effective. This research indicates a direction for further research into uncertainty, and risk control, issues affecting underground engineering works.<\/jats:p>","DOI":"10.3390\/e20070503","type":"journal-article","created":{"date-parts":[[2018,7,2]],"date-time":"2018-07-02T10:56:52Z","timestamp":1530529012000},"page":"503","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Entropy-Based Risk Control of Geological Disasters in Mountain Tunnels under Uncertain Environments"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5987-7526","authenticated-orcid":false,"given":"Yuanpu","family":"Xia","sequence":"first","affiliation":[{"name":"State Key Laboratory of Disaster Prevention &amp; Mitigation of Explosion &amp; Impact, the Army Engineering University of PLA, Nanjing 210007, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0392-8715","authenticated-orcid":false,"given":"Ziming","family":"Xiong","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Disaster Prevention &amp; Mitigation of Explosion &amp; Impact, the Army Engineering University of PLA, Nanjing 210007, China"},{"name":"School of Mechanical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}]},{"given":"Zhu","family":"Wen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Disaster Prevention &amp; Mitigation of Explosion &amp; Impact, the Army Engineering University of PLA, Nanjing 210007, China"},{"name":"School of Mechanical Engineering, Nanjing University of Science and Technology, Nanjing 210094, China"}]},{"given":"Hao","family":"Lu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Disaster Prevention &amp; Mitigation of Explosion &amp; Impact, the Army Engineering University of PLA, Nanjing 210007, China"}]},{"given":"Xin","family":"Dong","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Disaster Prevention &amp; Mitigation of Explosion &amp; Impact, the Army Engineering University of PLA, Nanjing 210007, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,7,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"216","DOI":"10.1016\/j.ijsolstr.2009.09.028","article-title":"Analytical solutions for collapse mechanisms in tunnels with arbitrary cross sections","volume":"47","author":"Fraldi","year":"2010","journal-title":"Int.
