Study on Model Experiment of Crushed Rock Layer Eliminate the Differential Settlement
Model experiment box for crushed rock layer to eliminate the differential settlement was designed. Through the model experiment, the effect of eliminating differential settlement was validated and the truth of it was analyzed. Then the concept and the expressions of the secondary loose coefficient was established. Through measuring the secondary loose coefficient of different rock layers by designed measure box, the relationships of grain diameter of crushed rock, grain figure of gravel and the friction angle with the secondary loose coefficient were analyzed respectively. The research indicated that (1) the design of model experiment box and the experiment was successful; (2) crushed rock layer which can eliminate the differential settlement mostly depends on its capability of secondary loose; (3) the secondary loose coefficient increases with grain diameter of crushed rock and the friction angle, and the secondary loose coefficient of crushed rock is always higher than that of the pebble at the same grain diameter.
