Description

Technical Field

[0001] The present invention relates to the technical field of active vibration reduction support, and in particular to a three-way multi-index evaluation method and medium for wave absorbing support technology. Background Art

[0002] Deep engineering projects face extremely complex geological conditions and high ground stresses and excavation disturbances, leading to frequent disasters such as rockbursts. After drilling and blasting, blasting stress waves propagate through the surrounding rock. Disturbing the critically high-stress surrounding rock, these waves can easily lead to disasters and pose a significant threat to the safety of personnel and equipment.

[0003] Currently, the control technologies used for explosion-resistant and vibration-reducing support in deep engineering projects mainly involve slit blasting to control the source of the explosion and the use of high-strength impact-resistant supports and steel arch supports in the surrounding rock. However, for deep hard rock projects, slit blasting reduces the power of the explosives, making it difficult to achieve the desired blasting results in high-stress hard rock. Deep engineering projects are subject to not only blasting stress waves but also seismic waves, rockburst waves, and other construction disturbances, all of which are difficult to control. High-strength impact-resistant supports and steel arch supports are extremely expensive and have complex construction procedures, making them difficult to promote and apply on a large scale. Therefore, it is of great significance to develop an active wave-absorbing support technology with low cost, mature construction methods, convenient construction, and broad application prospects to reduce the disasters caused by stress wave disturbances in deep engineering projects. The surrounding rock of deep engineering projects is mainly in a true triaxial stress state, but the current evaluation method for surrounding rock vibration mainly uses the shallow method, that is, a single analysis of the axial peak velocity of vibration, which cannot fully reflect the surrounding rock vibration characteristics under the true triaxial stress state and the vibration reduction effect of the stress wave inside the surrounding rock. Summary of the Invention

[0004] Based on this, it is necessary to propose a three-dimensional multi-index evaluation method and medium for wave-absorbing support technology to address the technical problem that the existing technology cannot fully reflect the vibration characteristics of the surrounding rock under the true triaxial stress state and the vibration reduction effect of the stress wave inside the surrounding rock.
