Among the various contributors to environmental vibration pollution in urban areas, rail transit vibration stands out as a significant source. Consequently, addressing this issue and finding effective measures to attenuate rail transit vibration has become a significant area of concern. An infilled trench can be arranged periodically along the propagation paths of the waves in the soil to attenuate vibration waves in a specific frequency range. However, the periodic infilled trench seems to be unsatisfactory for providing wide band gaps at low and medium frequencies. To improve the isolation performance of wave barriers at low to medium frequencies, a buried PT-WIB consisting of a periodic infilled trench and a wave impedance block barrier has been proposed in this paper. A three-dimensional finite element model has been developed to evaluate the isolation performance of three wave barriers. The influence of the PT-WIB\u2019s parameters on isolation performance has been analyzed. The results indicate that the combined properties of the periodic structure and the wave impedance block barrier can effectively achieve a wide attenuation zone at low and medium frequencies, enhancing the isolation performance for mitigating environmental vibration pollution.<\/jats:p>","DOI":"10.3390\/s23187666","type":"journal-article","created":{"date-parts":[[2023,9,5]],"date-time":"2023-09-05T10:26:43Z","timestamp":1693909603000},"page":"7666","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Numerical Analysis of the Mitigation Performance of a Buried PT-WIB on Environmental Vibration"],"prefix":"10.3390","volume":"23","author":[{"given":"Lei","family":"Gao","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Central South University, Changsha 410000, China"},{"name":"Department of Building Environment and Energy Engineering, The Hong Kong Polytechnic University, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenzhi","family":"Cai","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Central South University, Changsha 410000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9598-1478","authenticated-orcid":false,"given":"Chao","family":"Li","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Central South University, Changsha 410000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9510-2071","authenticated-orcid":false,"given":"Cheuk Ming","family":"Mak","sequence":"additional","affiliation":[{"name":"Department of Building Environment and Energy Engineering, The Hong Kong Polytechnic University, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1276","DOI":"10.1016\/j.scitotenv.2015.09.101","article-title":"The growth of railway ground vibration problems\u2014A review","volume":"568","author":"Connolly","year":"2016","journal-title":"Sci.
