BASIC EXPERIMENTS CONCERNING BEARING CAPACITY OF THE LIQUEFIED GROUND UNDER ASPHALT PAVEMENT

Abstract

 The mission of an airport during and after a great earthquake is important from a standpoint of its helpful function for emergency special operations of transporting relief supplies to the disaster area. However, it is expected that the function of runway will be lost due to differential subsidence and decrease in bearing capacity of the ground with excess pore water pressure induced by earthquake. In this paper, in order to estimate the bearing capacity of ground after liquefaction, a series of CBR tests and field tests were conducted. This paper describes the influence of excess pore water pressure to bearing capacity of runway ground during and after liquefaction.
