Tailored thermo-active geostructures for energy performance optimisation

项目问题：在城市环境中，地源能源系统通常通过将热交换器管道嵌入岩土结构（如桩基）来部署。尽管有明显的优势，但它们在英国的部署率远低于欧洲。这是由于人们更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学和力学性能。项目概述：该项目将探索量身定制的土壤和土桩系统的改进，以优化热性能和机械性能，并将解决热桩的长期机械响应。这个项目将包括实验和计算工作的结合。这将包括不同土壤类型、不同改良土壤、增强的土-桩界面和不同的土-桩配置的循环热测试，以及土-桩系统的有限元建模，以优化热活性土工结构的设计和性能。该项目将利用EPSRC与伦敦帝国理工学院合作的160万英镑的SaFEGround项目：可持续、灵活和高效的地源加热和冷却系统。

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.
