| Abstract: | An experiment was conducted to study the effects of stress level on compression and consolidation behaviors of swamps soft soil based on compression and consolidation experiments of swamp soft soil in Qiqihar region.The changing regularity of the main compression indexes with consolidation pressure were obtained,including e-p curve,compression factor,compression modulus,primary consolidation coefficient,and secondary consolidation coefficient.The effects of different load ratios on e-lgt curve,primary conso... |
