Derivation of Pore Water Pressure Coefficient for Continuous Porous Materials

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.
