Numerical Analysis on the Characteristics of Settlement Deformation of the High Rock-Filled Embankment during the Construction Period

Abstract:

Embankment filling is a process step by step. The influences of its filling height changes on the stress and deformation can not be reflected in a load. However, in the actual construction, it leads to quality accident in embankment construction that filling usually doesn’t control the thickness according to the requirement of construction specification. In order to reveal the stress and strain law of about 72 m high rock-filled embankment during the construction, and provide a scientific reference to construction quality control of the embankment, according to the typical cross section of the Hurongxi highway, using two loading modes to simulate the embankment filling, the internal stress, strain and corresponding graphics of different control points of the embankment under the various loads were presented. The results of the two loading modes are analyzed and compared. It shows that the settlement, stress and construction quality control points of the embankment are different and larger under the different loading
