- Abstract
The paper aims to research how the main parameters of the rock slopes with joint planes covered: Shear modulus, unit weight and the angles between the joint planes influence the stability and the failure modes of the slopes. The methods are to imitate the jointed rock slopes by the large-scale finite element simulation software, analyze and study the influences on the safety factors of slope and distribution or size of the equivalent plastic strain zones of above parameters with control variable method. The results show that: When the Shear modulus increase, the safety factors will also increase and the equivalent plastic strain zones will develop to the interior of the slope with obvious deformation. Unit weight of the rocks' increasing will make the safety factors decrease and the equivalent plastic strain zones develop to the crest and interior of the slopes with the area slightly increasing. The angles between the joint planes getting increased will make the safety factors decrease and the equivalent plastic strain zones develop to the interior of the slope with obvious deformation and the area decreasing. The examples show that: Shear modulus, unit weight and the angles between the joint planes have an important influence on the stability of jointed rock slopes
