Optimal determination method for bolt reinforcement parameters of rock mass slope with double sliding surfaces along the direction

Abstract

The present invention relates to an optimized measurement method for bolt reinforcement parameters of rock mass slopes, in particular to an optimized measurement method for rock mass slope reinforcement parameters with double sliding surfaces in the same direction, which belongs to rock slope stability evaluation and Landslide reinforcement and prevention field. An optimized method for determining the reinforcement parameters of rock mass slopes with double sliding surfaces, step 1: determining the basic morphological elements and physical and mechanical parameters of the slope to be reinforced; step 2: determining the overall stability coefficient of the rock mass slope; Three: Determine the rock mass slope stability correction coefficient, step four: determine the bolt layout and anchor bolt reinforcement anti-sliding force value, step five: determine the optimal incident angle of the prestressed anchor bolt of the rock mass slope, step six: determine the rock mass slope Reasonable anchoring length of body anchor. The beneficial effect of the invention is that the method can not only accurately measure the incident angle of the anchor rod, the radius of the anchor body and the anchor length, but also it is more economical, reasonable and safe to use the method to design the prestressed anchor rod.

Description

technical field [0001] The present invention relates to an optimized measurement method for bolt reinforcement parameters of rock mass slopes, in particular to an optimized measurement method for rock mass slope reinforcement parameters with double sliding surfaces in the same direction, which belongs to rock slope stability evaluation and Landslide reinforcement and prevention field. Background technique [0002] As one of the serious geological disasters in my country, landslides are extremely harmful and destructive, bringing huge economic and property losses to our country, and posing a serious threat to construction projects and people's lives. Among them, rock landslide is a common landslide geological disaster with great harm, especially when the rock mass slope has obvious structural plane, the landslide body is very easy to slide along the structural plane to form a landslide. Therefore, it has very important scientific significance and engineering application valu...
