Title: Centrifugal Model Test of Red and Soft Rock-filled Embankment
Abstract: Research purposes: This paper reasonably confirms the compacting parameter of red and soft rock-filled embankment through investigating the settlement characteristics of red and soft rock fillings under different compacting conditions. Research methods:This paper verifies the suitability of red soft rock-filling for embankment through the geotechnical centrifugal model test. Research results:The after-construction settlement of red and soft rock-filled embankment will gradually weaken with increasing of compacting parameter.Under the conditions of compacting parameters: 0.87,0.90,0.93,0.97 respectively,the ratios of final settlement after construction to heights of embankment are 2.4‰,1.913‰,1.833‰ and 1.673‰ respectively,which could satisfy the requirements of after-construction settlement control standard for subgrade as regulated in Temporary Regulations for Design of 200 km/h Railways. Research conclusions:Red and soft rocks could be used directly as embankment fillings and its compacting coefficient should be controlled above 0.93.This research outcome has a great significance for construction of the railways and highways in the areas covered with red and soft rocks.
