  1. The change regularities of lining pressure and the failure process of surrounding rocks in permeation which a special sand is used as model materials are successfully simulated. the basic theory is established for the study of same type and the scientific basis for the tunnel prop design in saturation rock is provided

    採用特定的河砂作為模型材料成功地模擬了破碎圍巖隧道在遇水情況下襯砌的受力變化規律及巖體的破壞過程，為開展同類型研究奠定了基礎理論，為飽水巖體隧道開挖支護設計提供了依據。
  2. The use of shotcrete as early linings of tunnel is a prevalent technique in underground engineering today. in cases with reliable rock situation, shotcrete linings can even be used as permanent prop for tunnel. the sfrc can act as a substitute for normal concrete and yields good results in such situation

    以噴射混凝土作為隧道初期支護是隧道工程實踐中一項較成熟的技術，在圍巖條件較好的一些工程中，噴射混凝土襯砌甚至可以單獨作為永久的襯砌使用。
  3. On the basis of model test, a better construction method under pre - prop for the surrounding rock i, ii, iii, named whole section excavation with heading in moderate degree and that with center heading and center partition first, then with two sides heading, is put forward

    在模型試驗的基礎上，提出了、 、類圍巖隧道在預支護下的優化施工方法，即下導洞適度超前全斷面開挖與先行中導洞及中隔墻、其次兩側下導洞適度超前全斷面開挖。
