Analysis on Control Indicators for Settlement and Deformation of the Rock-Filled Subgrade in Mountainous Area

To increase the stability of roadbed, the indexes of settlement control of half-filled and half-dug roadbed are analyzed and studied. First, assuming that the Poisson's ratio is a constant, the Prony series expression of the Merchant model is derived. Moreover, the subgrade settlement model was built using ABAQUS software. By calculation, the uneven settlement curve of road embankment under different working conditions is obtained. The curve...
