Subgrade Deformation And Stability Analysis Of The Rock-slag Mixture

In view of the situation that rock-slag mixture is used massively along the route in the XI-HAN highway, this article has carried out the systematic the experiment studies and the theory exploration about the classification of rock-slag mixture, physical mechanics character, intensity deformation and roadbed stability in the southern of SHAN XL The main research work including following aspect:1. It makes an investigation on hydro-geololgy condition of rock-slag mixture along along the route in the XI-HAN highway. The article expects having carried out definition to rock-slag mixture , carries on the classification to rock-slag mixture from the different aspect and has studies its gradation characteristic.2. The rock-slag mixture has conducted the more comprehensive experimental study, including the compaction test, the CBR experiment, the snapping back module experiment, the compressive strength test, immerses broken experimental and the inflation quantity experiment. It has carried on the lamination subsidence quantity observation, compactness experiment and the snapping back module experiment in the field test section.3. In foundation which in the domestic and foreign investigation and study and the room experiments, limits the theorem according to mechanics of plasticity in about, the lower limit theorem uses each vertical strip method center maximum value, but upper limit theorem approximate with slanting strip method, to different highly, the different decency degree and was different slope ratio descends a mountain the dregs material roadbed stability to carry on the computation and the analysis.4. The rock-slag mixture roadbed labor subsided after in the XI-HAN highway has carried on the longer time observation.
