Root reinforcement has recently been heralded for its eco-friendly attributes and efficacy in enhancing soil properties. Nonetheless, extant literature remains focused on individual soil types, often sidelining the biological influence of entities like roots. Moreover, a reliance on experimental measurements in prior studies has precluded exhaustive theoretical discourse. Addressing these lacunae, the present investigation was embarked upon. Two focal areas emerged: firstly, an intricate exploration, underpinned by both experimental and simulated data, of the correlation between pore attributes and thermal conductivity in root-reinforced silty clay, and the concomitant repercussions on shear strength. Secondly, an encompassing appraisal of the thermal stress within this reinforced clay was conducted via a temperature-seepage-stress coupling model. Marigold root-soil composites became the central subjects, with an aim to discern the influence of herbaceous Asteraceae plants endemic to Taihang Mountain on parameters such as erosion resistance, soil consolidation, and shear resistance augmentation of soil masses. By harnessing raw soil samples, fashioning test specimens, and executing controlled triaxial compression experiments, intricate patterns pertaining to erosion resistance and soil consolidation, modulated by varying factors like root content, soil depth, and moisture content, were elucidated. The revelations herein promise to refine predictions of thermal conductivity and deepen the comprehension of shear strength dynamics in multifaceted soil scenarios.","PeriodicalId":13995,"journal":{"name":"International Journal of Heat and Technology","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136034867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their rapid construction and environmentally friendly characteristics have rendered them a favoured choice within the engineering community. However, under high-temperature conditions, such as in fires or high-temperature industrial processes, concerns remain about the temperature distribution within these culverts and the subsequent impact on joint performance. Although some studies have addressed the temperature distribution and thermal effects associated with these culverts, most have been grounded in theoretical assumptions or have only engaged in preliminary experiments. In this research, an in-depth analysis of the temperature distribution within prefabricated box culverts under high-temperature conditions and the implications for joint performance is undertaken. Advanced finite element analysis tools are utilised for simulations. The findings provide the engineering community with comprehensive and precise reference data, holding significant implications for the design, construction, and maintenance of future prefabricated box culverts.","PeriodicalId":13995,"journal":{"name":"International Journal of Heat and Technology","volume":"383 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136034845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
