ABSTRACT

A sprayed waterproofing membrane whose base material is a polymer has a higher initial strength and faster construction time than conventional sheet-type waterproofing materials. Because of its high physical properties, such as adhesion and tensile strength, the shotcrete or concrete reinforced with waterproofing membrane shows as composite materials. In this study, to consider an application to the conventional design method, the numerical method was used. In the numerical analysis, material and contact properties were adopt from previous studies. Because the contact properties between membrane and other supporting materials at the interface is important parameter to understand the supporting mechanism of the sprayed waterproofing membrane, contact properties were mainly considered at the interface. In addition, the conventional design method for the tunnel lining, was reviewed with numerical results.
