摘要
根据有效应力理论 ,以弹性理论和混合物理论为基础导出非饱和黏土孔隙压力的一般公式 ,由此得出各向同性压缩和侧向约束压缩两种情况下的孔隙压力计算公式 .并对此两种情况进行试验证实。结果表明 ,导出的孔隙压力公式与Skempton公式构成一致 ,其中系数B的试验结果中显示毛细压力对孔隙压力有一定的影响。
In this paper applying the elastic deformation theory and theoretical gas law, and assuming the conservation of mass , a general pore pressure formula has been derived,which is consistent with the Skempton formula in form, and can be used to derive the pore pressure of soil specimen under isotropic compression and confine compression.The experimental results have been presented to validate the academic theories. It shows that the capillary action has a little influence to pore pressure.
