Problems solved by technology

Therefore, when the external environment or internal properties change, the rock mass slope will show an extremely complicated deformation and failure process, so that it is difficult to determine the real stress-strain state in the slope rock mass, and the failure theory expressed by stress or strain It is difficult to reflect the real mechanical state of the rock mass

Embodiment 1

[0035] The bedding rock slope belongs to layered rock mass. The sequence numbers of rock formations from the top to the foot of the slope to be analyzed are 1, 2, ..., i, ..., n.

[0036] This embodiment discloses a method for analyzing the stability of bedding slope excavation based on deformation. Taking the excavation and unloading load as the starting force of slope deformation, the excavation stability coefficient K of the slope is calculated.

[0037] see figure 1 , the bedding slope is in the state of active lateral pressure before excavation, and receives the active lateral pressure E pointing out of the slope a . After excavation, the active side pressure becomes the static side pressure E 0 . This change in lateral pressure will lead to the unloaded state of the slope, resulting in a certain unloaded rebound deformation, which is defined as the deformation induced by the excavation of the bedding slope. It is assumed that the potential sliding surface is the in...

Abstract

The invention provides a deformation-based method for analyzing the stability of bedding slope excavation. The method includes the steps of surveying and surveying, using excavation unloading load as the starting force of slope deformation to calculate the excavation stability coefficient of the slope, and analyzing the stability of the slope. This method can determine the stability state of the slope in real time based on the slope shoulder displacement, and provide a targeted basis for the prevention and treatment of bedding rock mass landslides.

Description

technical field [0001] The invention relates to the technical field of rock and soil slope stability, in particular to an analysis method for the dynamic stability of bedding rock slopes. Background technique [0002] In engineering practice, because slope rock mass often has complex structural planes and structures, and is in a complex in-situ stress field, there are many unknown and uncertain influencing factors. Therefore, when the external environment or internal properties change, the rock mass slope will show an extremely complex deformation and failure process, so that it is difficult to determine the real stress-strain state in the slope rock mass, and the failure theory expressed by stress or strain It is difficult to reflect the real mechanical state of the rock mass. [0003] Because the displacement itself is easy to monitor, the stability of the rock mass structure can often be judged according to the displacement of some special positions on the structure. Th...
