Development of quality management for high pressure injection mixing methods

Abstract

High pressure injection mixing methods are extensively used for seismic reinforcement, prevention of liquefaction. On the other hand, since the cement improvement foundation has the high non equality, the quality of improvement is greatly influenced by foundation conditions.Therefore,it is necessary to propose the new quality management from a subject occurring in the conventional quality management.In this paper, we report the new quality control technique to the cement improvement foundation by a high pressure injection mixing methods.
