Applied Investigation On The Archoring Mechanism Of Two Different Anchors And Engineering Application

With the emergence of a large number of highway tunnels, subway tunnels, high-risebuildings, deep pit and underground engineering, anchoring techniques are increasinglysubject to our attention. bolting technology, in particular, is now widely used in various fieldsdue to its many other advantages. Bolting Technology will provide tremendous help togeotechnical engineering construction and vast opportunities for its own development.This paper,①Basically mastered the mechanics mechanism of bolt supportingengineering, analyzed three kinds of damage form of expanding bolt through the theoreticalderivation and application research;②Derived the reinforcement force formula of boltingengineering;③Provided bolt arrangement, parameter design, anti-corrosion design,deduced the anchor bolt length formula;④Obtained the influence of enlarge hole diameterand soil properties to the bolt anchorage force Through the model test;⑤Developed finiteelement software analysis results with the model test, thus enhancing the reliability of thetest results.Finally, based on a in situ project in Foshan, the present paper made a summary of theanchor construction of pile-anchor support engineering technology,analyzed and selectedBolting program.This paper also explored the technical means and monitoring law of anchorconstruction,it introduced the points of drilling, anchor production and placement, grouting,tension and lock construction,and monitoring content, monitoring methods and monitoringtime of the support system.This paper starts from the anchoring engineering research analysis;explored theapplication status of bolting technology; Analyzed the mechanisms of the bolt work process;Provided mechanical basis for bolting design; The model test and finite element numericalanalysis provided design reference to new technology of ends reaming bolt; Improved theanchor construction technology and developed bolting monitoring, which helps constructionpersonnel to better achieve the intent of the designers.
