Project problem:In urban settings ground source energy systems are commonly deployed by embedding heat exchanger pipes into geotechnical structures, such as piled foundations. Despite obvious advantages, their deployment rate in the UK is considerably lower than in Europe. This has been attributed to greater concerns of the impact of temperature variations on structural safety and the long-term inter-related thermal and mechanical performance of those structures.Project summary:The project will seek to explore tailored improvements in the soil and soil-pile system for optimised thermal and mechanical performance and will address the long-term mechanical response of thermal piles. The project will involve a combination of experimental and computational work. This will include cyclic thermal testing of different soil type, different improved soils, enhanced soil-pile interface, and different soil-pile configurations, and the finite element modelling of the soil-pile system to optimise the design and performance of thermo-active geostructures. This project will capitalise on and be aligned to the £1.6M EPSRC SaFEGround project: Sustainable, flexible and efficient ground-source heating and cooling systems, in collaboration with Imperial College London.

项目问题：在城市环境中，地源能源系统通常通过在土工结构(如桩基)中嵌入热交换器管道来部署。尽管有明显的优势，但它们在英国的部署率远远低于欧洲。这是由于人们更加关注温度变化对结构安全的影响，以及这些结构的长期相互关联的热性能和力学性能。项目摘要：该项目将寻求对土壤和土-桩系统进行量身定制的改善，以优化热性能和力学性能，并将解决热桩的长期力学响应。该项目将涉及实验和计算工作的结合。这将包括对不同类型的土壤、不同的改良土壤、增强的土-桩界面和不同的土-桩结构进行循环热试验，以及对土-桩系统进行有限元建模，以优化热力地质结构的设计和性能。该项目将利用并与GB 160万欧元的EPSRC SaFEGround项目保持一致：与伦敦帝国理工学院合作，提供可持续、灵活和高效的地源供暖和制冷系统。
