為此，本論文提出一種新的錨桿計算模型，它將錨桿與周圍巖土體間的相互作用作為接觸問題考慮，其計算理論比較嚴謹，能較好地模擬出錨桿的受力狀態及錨桿與巖土體間的剪切?滑移作用，即：錨桿?巖土體之間的接觸面具有抵抗強度，當接觸面上切向應力小於其抵抗強度時，錨桿與巖土體共同變形；達到抵抗強度時則沿切向發生相對滑動。

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
