Abstract
In order to research the effect laws of pore water pressure on stability of surrounding rock of roadway of high stressed soft rocks in deep,the finite difference program is used to simulate the stability of surrounding rock with different pore water pressure and the distribution laws of water pressure.The results show that,Along with the pore water pressure increases,stress concentration value in surrounding rock and concentration range increases,the distance from the biggest stress concentration position to the mid-point of the roadway tends to gradually fixed value;And along with the pore water pressure increases,displacements of two sides measured resulted from pore water pressure than roof,roof is greater than floor,therefore,the key of surrounding rock with pore water pressure management is deformation of two sides control.关键词
