  2. Secondly, grounded on the study of the distribution of the high external waterpressure and high geostress and the characteristic of the rock in engineering area, the paper built the elastoplastic fem numerical simulation model, and think over the procedure in tunnels excavation and the history of work of water load, and then get the relations between the different tunnels diameter, different permeability coefficient and depth of the grouting rock and the deformation, stress distribution and plastic range of the surrounding rock and support structure. finally, according to the modern design theory of tunnels construction, the particular design of country rock reinforcement and support structure are researched and presented for diversion tunnels

    接著，本文在深入研究工程區高外水壓力及高地應力分佈規律及巖體特性的基礎上，建立起高地應力、高外水壓力作用下隧洞圍巖結構非線性有限元模擬計算模型，然後考慮隧洞的開挖過程、水荷載的作用歷史，通過計算分析得出了不同洞徑、不同的灌漿圈滲透系數和不同的灌漿圈深度以及不同開挖過程與圍巖及支護結構的應力、位移和塑性區的關系。
  3. The results are important for dam base excavation and engineering disposal. ( 2 ) arch dam can be regarded as an elastic ground cantilever system composed of vertical cantilever, horizontal arch, and torsion structures. the dissertation takes the arch dam as load diversion system of arch - cantilevers system located on the ground composed of elastic cantilever

    （ 2 ）將拱壩虛擬為由座落在壩基塊體有限元上的一系列懸臂梁與水平拱組成，將懸臂梁視作由水平拱所支承的彈性地基梁，考慮徑向和切向調整，比以往的彈性地基梁只考慮徑向調整有所發展；而且用塊體元模擬壩基，也能較精確地模擬壩基多種斷裂構造等對壩體結構行為的影響。
