  1. Fist of all, on the basis of the research of agone boffins, this author investigates the interaction mechanism of bolts and rock, and introduces the elastic ? lastic analytical resolution which is consist of the liner structure, the equivalent reinforced wall rock and the original wall rock in the simple loading from the equivalent well - proportioned view ; this solution is very important meaning for the engineering design. on the basis of coulomb friction model, the author introduces the finite element equation of the contact problem in order to provide the academic foundation for the application of msc. marc. finally, combining the engineering practice of the non - linear analysis of shield tunnel through yellow river of the south - north water transfer and using the model of friction, the author researched the evolution law of stress and displacement field in the structure of grouted rock bolts, and analyzed the effect to the stress and deformation of surrounding rock mass due to anchor supports

    首先,在前人研究成果的基礎上,對錨桿與圍巖的相互作用機理進行研究,利用全長錨固錨桿的中性點理論,從效均化的角度來考慮錨桿對圍巖的加固作用,並推了在簡荷載作用下,含有襯砌、效加固后的圍巖、原始圍巖三者的彈塑性解析解,對工程設計有著重要的參考意義;在數模擬方面,以考慮錨固圍巖滿足規則化庫侖摩擦模型為基礎,利用虛功原理推了接觸問題的有限元方程的計算格式,為開發運用大型商用有限元軟體msc . marc提供了理論據,也形成了本文的理論基礎:最後,論文以南水北調東穿黃隧洞穩定性分析項目為工程實例,利用本文所述的接觸問題的摩擦模型理論,對錨桿支護結構的應力場、位移場的變化規律進行了研究,分析了加錨支護對隧洞圍巖應力、變形的影響。
  2. On the premise of summarizing former contributions in the field, and considering the universality of the cylindrical space with circular cross - section in industry, the author develop a novel ofpt structure, on which the design theories, numerical simulation, design of experimental system for plane structure, preliminary experiment and design of applied space structure are presented. the main contents of the thesis are that : put forward the novel ofpt pixel distribution and plane - light - path design theories and their empirical formulae. the numbers of the ofs units and their emitting rays can be decided by the requirements of image - reconstructed resolution and the size of the center unmeasured region

    本論文在總結前人工作的前提下,充分兼顧了工業中具有圓形截面的圓柱形容器或管道普遍存在的事實,提出了一種新型的光纖過程層析成像結構,並從理論設計方法,具體結構模擬,平面結構實驗系統設計,初步實驗以及空間結構實用化設計、理論分析方面進行了研究,主要的創新點在於:提出了一種用於工業過程監測與控制的新型光纖過程層析成像結構設計方法,並推了該方法的經驗公式,該方法主要包括像素分配和平面光路結構設計,可以據工程應用中圖像重建的解析度和圓形截面非測量區域所佔比例的要求,設計所需傳感元的數目和傳感元發射光的數目;設計了一種新型的光纖過程層析成像結構,並對該結構進行了可行性分析和數模擬。
