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
首先，本文在綜合分析隧道穩定性影響因素及失穩破壞模式的基礎上，對全長粘結式砂漿錨桿作用力學機理進行了深入研究，為全長粘結式砂漿錨桿的有限元模擬分析奠定了基礎;其次，針對傳統錨桿有限元模擬方法的局限性與不足，在上述全長粘結式砂漿錨桿作用力學機理研究基礎上，建立出能反映界面非線性粘結的新型復合砂漿錨桿有限單元模型;然後，運用上述復合砂漿錨桿單元模型，引進非線性有限元分析手段，開發了隧道支護穩定性分析的有限元程序，並就全長粘結式砂漿錨桿的型式與設計參數對支護效果的影響進行了深入探討，得到了對隧道支護設計具有指導意義的結論;最後，運用本文研究成果對某公路隧道工程實例進行了開挖與支護的模擬計算，探討了其應用方法，並就隧道變形與應力及塑性區分佈規律進行了分析，從而提出了合理的支護方案，為隧道支護設計提供了參考依據，完善了隧道全長粘結式砂漿錨桿支護的理論與方法。 -
This paper uses of the actual mechanics form, cantilever bending stiffness is adopted in the mega structure, however shearing stiffness in the sub structure. based on the complex mode theory, this paper gains the expression of dynamical response of the system based the model of municipal no. l building of tokyo city and analyses the affection of the main parameters ( stiffness and damping ) on the two configurations ( sustaining type and hang type ). the results indicate that the rational stiffness of the sub structure can control the deformation of the mega structure perfectly, but the acceleration of the sub structure increases at the same time
本文採用了更接近實際的力學模型，主結構採用彎曲剛度，子結構採用剪切剛度，利用隨機振動復模態理論，推導了巨型框架減振結構的動力響應表達式，並以日本東京市政一號樓為基本模型，討論了巨型框架減振結構兩種結構形式（座承式和懸掛式）的主要參數（剛度和阻尼）對減振效果的影響，結果表明：與普通巨型框架結構相比，減振結構通過合理選擇子結構剛度，可以較好的控制主結構在順風向脈動風作用下的位移響應，從而提高結構的安全性，但與此同時，子結構自身的加速度響應也有了一定程度的提高。 -
