Abstract In light of the first underground gas2storage engineering in China , the principles of underground gas2
storage caverns with water curtain are presented. Analysis and discussion of the water curtain f rom theory are car2
ried out by finite element method. Numerical simulation result s give a good proof that using water curtain to stor2
age L PG (Liquefied Pet roleum Gas) in underground is safe. It will provide quite valuable reference for the design
and const ruction of gas2storage cavern in China.
