Abstract

The invention relates to a method for optimally measuring reinforcing parameters of a rock slop anchor rod, in particular to a method for optimally measuring reinforcing parameters of a forward doublesliding surface rock slope anchor rod, and belong to the field of rock slop stability evaluation and landslip reinforcement and prevention and cure, the method comprises the following steps of: 1, determining basic morphological elements and physical mechanical parameters of a slope to be reinforced; 2, determining an integral stability coefficient of the rock slope; 3, determining a stability correction coefficient of the rock slope; 4, determining anchor rod layout and an anchor rod reinforcing anti-slip force value; 5, determining an optimal incidence angle of a rock slope pre-stressed anchor rod; 6, determining a reasonable anchoring length of the rock anchor rod. The method has the advantages that the incidence angle of the anchor rod, the radius of the anchor solid and the anchoringlength can be accurately measured, and the pre-stressed anchor rod is designed to be more economical, more reasonable and safer by using the method.

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...
