Abstract:The structure of soft clay has great influence on the physico-mechanical property of the soil body,particularly on the consolidation deformation and the flowing rate of liquid of the soil body.Currently,this aspect is still a hot issue. The refitting K0 consolidometer is used,and the experiment of consolidation or permeability can be performed on this instrument at the same time. According to the experiment of K0 consolidation and permeability of natural soil and remolded soil,the influences of the structure of soft clay on the flowing rate of a liquid are analyzed,and the calculation formula of coefficient of permeability and pore ratios are proposed. According to the trial analysis of strain characteristic of soft soil,the structural strength of the soil body is used to reflect the influence of soil body transform. Based on the foundation of the analytical deformation mechanism,the settlement-computing method that considers the soil body structure is put forward. According to the definition,the new method of the permeability of consolidation is presented. This computation method avoids the weakness of traditional method and can be performed on the COBOL. Through the example of engineering on Dazhou—Chongqing Highway,the measured results of the highway foundation is compared to the result of the method,and the availability of this method is verified.
