TY  - JOUR
AB  - Thermo-active  structures  are  underground facilities which  enable  the  exchange  of  thermal  energy between the ground and the overlying buildings, thus providing renewable means of space heating and cooling.  Although  this  technology  is  becoming  increasingly  popular,  the  behaviour  of  geotechnical structures under additional thermal loading is still not fully understood. This paper focuses on the use of  underground  tunnels  as  thermo-active  structures  and  explains  their  behaviour  through  a  series  of finite  element  analyses based  on  an  existing  case  study  of  isothermal  tunnels  in  London  Clay. The bespoke finite element codeI CFEP is adopted which is capable of simulating the fully coupled thermo-hydro-mechanical behaviour of porous materials. The complex coupled interactions between the tunnel and  the  surrounding  soil  are  explored  bycomparing  results  from selected types  of  coupledand uncoupled simulations. It is demonstratedthat: (1) the thermally-induceddeformation of the tunnel and the ground are more critical design aspects than the thermally-induced forces in the tunnel lining, and (2) the modelling approach in terms of the type of analysis, as well as the assumed permeability of the tunnel lining,  have  a  significant  effect  on  the  computed  tunnel  response  and,hence, must  be  chosen carefully
