AI Technical Summary
Existing technologies cannot effectively simulate the effects of groundwater infiltration on foundation concrete structures in freeze-thaw soil environments, leading to inaccurate assessments of building foundation safety.
A freeze-thaw cycle test method for building foundation concrete was adopted using a simulation chamber. Water seepage into the bottom of the simulation chamber was used to simulate groundwater infiltration, and cold air cooling and electrothermal radiation were combined to simulate freeze-thaw cycles to test the performance changes of concrete specimens.
It can more accurately simulate the performance changes of building foundation concrete in freeze-thaw environments, thus improving the ability to assess and monitor the safety of building foundations.
