16 Artificial Ground Freezing to Form Walls in Taiwan
COVER STORY
Yung-Wen Chen and Ting-Wei Wang
Since 1962, ground freezing has been applied to more than 600 sites in Asia,
using both brine as well as liquid nitrogen for freezing. Both methods are
effective in various soil and ground conditions, and ground freezing has been
proven as a viable, versatile construction alternative for both shield tunnel
excavation and groundwater control.
