Initial results of study on appropriate prefabricated vertical when dealing with poor underlying soil conditions by method of mernard vacuum consolidation

Abstract

     When constructing structures on poor underlying soil conditions, the most concerned issue is to improve the soil conditions to reduce subsidence, strengthen the ability of the foundation to support load and reduce its seepage in the shortest time with the most economic consideration. Mernard Vacuum Consolidation, born in developed countries, are now being applied in Vietnam and has had good results. According to this method, one of the factors affecting its effectiveness is the distance between prefabricated verticals. Initial results of study on choosing appropriate distance between prefabricated verticals are introduced in this writing to support the above mentioned method.
