Application Analysis of Anchor Bolt Support Technology in Highway Construction
In order to improve the stability of anchor bolt support in highway construction,the application of bolt support technology in highway construction is studied in detail,taking Deyun Expressway Gaotang section project as an example.In the course of the study,the changes of the internal and external loads of the supporting structure in different design and construction stages are fully consid-ered,and injected grout,completed the construction of highway bolt support.It is found that the increase of bolt length has a positive effect on the stress distribution around the slope in the limit range.The deformation of the three groups tests is controlled within 0~80 mm,and the deformation decreases after 15 days of monitoring,the stability of support has been greatly improved.The test results show that the method can effectively restrain the initial deformation of slope,reduce the risk of deformation and failure of slope surface,and show a good supporting effect.
