摘要：<p>An underground storage reservoir for fluids such as liquefied gases consists of a container of reinforced concrete which is embedded in a shell of gravel and frozen water. The shell of gravel and frozen water. The shell is kept frozen by the contents or, if not cold enough, by embedded refrigerating coils. The outer periphery of the shell at the contact with the native rock is formed by an artificial heating zone. This eliminates the extra pressure on the container walls, which is otherwise caused by the volume increase of the shell when water transforms to ice.</p>
