grouted bolt 中文意思是什麼

Bolt has been in wide use as a kind of support in tunneling, especially fully grouted bolt. but the design method for fully grouted bolt is limited due to the shortage of it ’ s support effect mechanism at present

錨桿尤其是全長粘結式砂漿錨桿是隧道工程廣泛應用的支護型式，但由於目前對全長粘結式砂漿錨桿支護作用力學機理認識不足，使其設計方法存在一定的局限性。

So in this thesis an in - depth exploration of the finite element simulation of fully grouted bolt will be done starting from the study of mechanics mechanism of fully grouted bolt, the result will provide reference for the design of fully grouted bolt and this have value of theory and engineering

為此，本文擬從研究全長粘結式砂漿錨桿的作用機理入手，深入探討其有限元模擬方法，進而為隧道全長粘結式砂漿錨桿的設計提供參考依據，具有重要的理論與工程實際意義。

Secondly, in view of the limitation and shortage of traditional simulation of finite element approaches for bolt, a new composite grouted bolt element including nonlinear contacting relation will be built based on the above study of the mechanics mechanism of fully grouted bolt. then, an elastic - plastic finite element program will be developed for the analyses of tunnel stability, in which the composite grouted bolt element and nonlinear finite element analysis method will be used ; the patterns and the affect of main design parameters on the support effect of bolt will be analysed using the program, and conclusions of guidance importance for tunnel support design will be drawn. finally, simulation compution for the excavation and support of a highway tunnel will be made out using the above production, and the method of application of the program will be discussed ; analysis of the deformation, stress and distribution of plastic range will be done, and rational support plan will be worked out, which is of guidance importance for tunnel support design and the thery and technique of fully grouted bolt used in tunneling will be perfected further
