Above all, during the research of the automatic of hydrotechnics designs, the author has successfully developed the cad software autosd for hydraulic runnel design, and realized the function of immediate interpose among program and relief maps and the overall process computer aided function during the hydraulic tunnel design
總之，本文通過對水工設計自動化的研究，成功開發出水工隧洞輔助設計軟體autosd ，並首次實現在軟體運行時與地形圖的即時交互和反饋功能，實現了水工隧洞設計全過程的輔助設計功能。 -
Obtain these chief research achievements. ( 1 ) the method of hydraulic fracturing, kaiser effect experiment and the finite element numerical simulation computation results, the direction of maximum horizontal principal stress intersect the small - angle of tunnel axial line, it is favorable to the stability of tunnel peripheral rock ; according to the test rust of field stress - relief method, at the present time, zhe gu mount tunnel have n ' t access to high crustal stress site, maximum principal stress magnitude is 17mpa ~ 20mpa
主要獲得以下研究成果： （ 1 ）綜合水壓致裂法、室內巖石kaiser效應試驗和有限元數值模擬計算研究成果，最大水平主應力方向與隧道洞軸線小角度相交，對隧道圍巖穩定性有利；根據現場應力解除法測試結果，目前鷓鴣山隧道尚未進入高地應力段，最大主應力量級為17mpa 20mpa 。 -
The main work is done with the help of model experiment. in the flood - relief experiment, the flood carrying capacity of spillway tunnel is checked. in the hydraulic experiment of the diversion power conduit system, the followings are studied : the flow condition and fluctuation in the surge chamber, the distribution of flow velocity before the rack in the surge shaft, the amplitude of stage in the quick gate bay etc. the test step, content and results of different proposals are introduced in details
本項優化試驗研究的目的主要在於，通過泄洪系統整體水力學試驗，校核泄洪洞的泄流能力；通過發電引水系統整體水力學試驗，研究調壓井內水流流態和水位波動情況、調壓井內攔污柵前流速分佈情況；確定快速閘門井內水位波動幅度；試驗確定壓力管道水擊壓力穿井系數以及泄洪洞弧形門處的水壓力。 -
Due to the special relief in narrow mountainous zone, as well as the high cost of and the difficulty in applying separate tunnel line, twin - arch tunnel is adopted
在山區狹窄地帶等特殊地形條件下，採用分離式隧道線路較為困難且造價高昂，於是產生了雙連拱隧道形式。 -
Moreover, even if the proposed tunnel option is shown to be not causing any significant impacts to the long valley ecosystems, this is only a temporary relief to long valley which however is still unprotected and can be destroyed by legitimate land use changes e. g.,
即使隧道方案證實不會對?原的生態系統構成重大影響，此舉只能暫緩問題。 ?原仍未受到保護，根據現時的農業用途分區， ?原或會受到合法的土地用途轉變如乾耕農地用途破壞。 -
Even if the proposed tunnel option is shown to be not causing any significant impacts to the long valley ecosystems, this is only a temporary relief to long valley which however is still unprotected and can be destroyed by legitimate land use changes e. g., dry agriculture use under the existing agriculture use zone
縱使建議的隧道鉆挖方案證實不會對?原生態系統造成嚴重的影響， ?原亦只是暫且逃過一劫，尚未得到正式的保護，隨時會因?原屬于農業用途用地，而遭合法的土地用途改變如乾耕農地破壞。
