Method used for analyzing expansion mechanisms of anchoring bodies of different expanding agent contents through CT scanning

Abstract

The invention provides a method used for analyzing expansion mechanisms of anchoring bodies of different expanding agent contents through CT scanning. According to the method, high strength carbon fiber cloth coated PVC pipes are used for providing constraining force so as to prevent broken of PVC pipes because of anchoring body expansion, and simulating crustal stress constraint conditions. Glassfiber anchor poles are used for replacing metal anchor poles, in other words, nonmetal members are used for replacing metal members, so that problems that ghosting of metal in CT scanning is caused,and relative large influences on the internal CT values of anchoring systems are caused are solved; at the same time, a positioning part is adopted for accurate positioning scanning, the compactness degree value of expansion cement slurry in the anchoring systems of different expanding agent contents under the effect of crustal stress and underground water can be factually reflected by the CT value difference of different positions and the change rules with time passing, the expansion mechanisms of the anchoring bodies of different expanding agent contents are obtained at last, and reference and research application value are provided for practical engineering slope support protection.

Description

Technical field [0001] The present invention relates to the field of anchor solid expansion mechanism, and in particular, the present invention relates to a method for analyzing the expansion mechanism of anchor solids with different contents of expansion agents by CT scanning. Background technique [0002] CT scanning technology is a non-damage detection technology. It has been widely studied and applied because of its convenience, high safety, and intuitive results. CT scan can dynamically and quantitatively measure the changes in the internal structure of the material during the stress process. The resulting image can directly reflect the internal defects and damage of the object, and can quantitatively analyze the defects and damage. The working principle of CT scanning technology is to use X-rays to scan a certain section of the detected object from multiple directions under the non-destructive state of the tested component, and use a special detector to collect the informat...

AI Technical Summary

Problems solved by technology

Using glass fiber anchors instead of metal anchors, that is, replacing metal components with non-metallic components, solves the problem that the presence of metal in CT scans will produce ghosts, which will have a greater impact on the CT value inside the anchoring system.
