| 摘 要： | 介绍了测试煤样在３轴应力状态下，由于孔隙水压的作用而引起煤体固结变形的实验方法。实验表明，这种固结变形随作用于煤样上体积应力的增加呈负指数规律变化，而随孔隙水压的增加呈正指数规律变化。这一实验结论为岩石水力学学科中有效应力的研究揭示了新的规律，具有重要意义。

| Abstract: | A method was described in detail for testing consolidation deformation due to pore water pressure of coal samples under triaxial stress- The test conclusions show that the consolidation deformation varies respectively with the volumetric stress and pore water pressure in negative and positive exponential curves. The results present a new law for studing effective stress in rock hydraulics. |

| Keywords: | pore pressure volumetric stress consolidation deformation constitutive equation |
