Abstract

PURPOSE: To measure a frozen earth pressure without any concentrated stress when it has a high rigidity by means of an earth pressure meter provided with a load cell between a reaction plate and a pressure receiving plate of an earth pressure measuring device.
CONSTITUTION: When the subsoil is cooled by a cold heat of a liquid stored in an underground tank, it begins to be frozen from the external surface of a wall body 1. As the frozen earth 2 becomes thick, a pressure of a frozen earth exerts on the wall body 1 with a freezing expansion and further on a pressure receiving plate 6 of an earth pressure meter 4. In this process, a load cell will be compressed slightly more than the wall body under a pressure. But a slight projection of the pressure receiving plate 6 from the external surface of the wall body makes the rigidity of the wall body slightly larger than that of the earth pressure meter when the pressure exerts thereon thereby relaxing the concentrated stress on the wall body.
