A new climatic chamber adapted to the mini-centrifuge for simulating soil drying
Résumé
Drought is one of the extreme events that is expected to occur with greater frequency in the world affecting soil and foundation structures. This phenomenon depends on the water content in the soil and variables such as temperature, wind velocity, and sun radiation. To simulate the effect of these variables on soil, climatic chambers have been created; however, there are no studies that include all the environmental variables that generate desiccation in soil layers. In this work, a new climatic chamber adapted to the mini-centrifuge has been designed. This chamber consists of two connected containers. The first one is designed to contain water with salt in order to control the relative humidity; the second one is designed to contain the soil and to receive the airflow. In addition, air and soil are heated with three infrared lamps simulating sun radia-tion. This paper describes the design of the chamber, operation rages, facilities and preliminary results.
