    摘要:

    进行连续多孔材料的应力计算对分析其上部建筑物变形及稳定有着重要意义。连续多孔材料的实际应力及孔隙水压力系数是计算整体连续多孔材料受力的关键参数。利用弹性力学方法对饱和连续多孔材料进行受力分析,推导了连续多孔材料的实际应力与孔隙水压力的关系表达式,对连续多孔材料在轴对称应力状态下的两种受力情况进行了变形分析,分别推导了两种情况下材料的孔隙水压力系数表达式,并给出了试验验证方法。研究成果对连续多孔材料在基础工程中的应用具有指导意义。

    Abstract:

    The stress calculation of continuous porous materials is very important for analyzing the deformation and stability of the upper building. The actual stress of the continuous porous material and the pore water pressure coefficient is the main parameters for calculating the force of the overall continuous porous material. The elastic mechanical method is used to analyze the stress of saturated continuous porous materials. The relationship between the actual stress and the pore water pressure of unremitting porous materials is derived. The two stresses of continuous porous materials under axially symmetric stress are deformed. The analysis of the pore water pressure coefficient of the material in two cases is deduced, and the experimental verification method is given. The research results just have to guide significance for the application of continuous porous materials in basic engineering.
