( 4 ) according to the results of calculation and the characteristic of the landslide, it is suggested that such measures as unloading at upper part, anchorage and pile supporting system and drainage system should be used on the landslide. ( 5 ) according to geological investigation, there are three kinds of dangerous rock in the engineering, those are failing - down rock, collapsing rock and sliding rock
因此有必要對滑坡進行治理； （ 4 ）根據滑坡推力計算結果和本滑坡屬牽引式滑坡的特點，滑坡體上部相對較穩定，中下部處于基本穩定或不穩定狀態，因此建議此滑坡治理採用上部削坡減載與錨拉抗滑樁、擋墻進行支擋結合的處理方法，同時結合截排水等措施進行綜合治理； （ 5 ）根據地勘資料，通過對危巖體的形態、規模、基座和底界層及分佈特點和分析，將本工程危巖體失穩崩塌的方式歸納為墜落式、傾倒式和滑塌式三種類型並分別提出相應的穩定性計算方法； （ 6 ）分別對本工程中的危巖體進行了穩定性計算，並且發現其都處于不穩定狀態，因此根據實際情況分別提出相應襯砌支撐和清理等加固治理措施，最後還對加固后的危巖體進行了校核計算，滿足要求。The construction of the multiple - arch tunnel is deeply related to the form of center partition, the tunnel ' s section and excavation method etc. the change regularities of stress field caused by excavation are studied by 4 multiple - arch unlined tunnel model tests. the difference in lining for various multiple - arch sections is analyzed and the mechanics characteristics of center partition is discussed. then, a reasonable construction method for multiple - arch tunnel and a better section are put forward
通過4個連拱模型試驗，研究了連拱毛洞開挖引起的應力場變化規律，對不同的連拱斷面的襯砌受力差異進行了深入的分析，同時對中隔墻的受力特點也作了探討，提出了合理的連拱隧道構築方法及優化斷面圖。When there is original stage support only, the load ratio of surrounding rock gets more and more bigger with the increasing of crust stress, correspondingly, the load ratio of initial stage support gets smaller. when the initial stage support and the second support act each other, the load ratio of surrounding rock is more than fifty percent, and it has little change with the increasing of crust stress. the whole analysis of the surrounding rock and support shows that the bottom arch of liner and the feet of liner have serious stress concentration, so do the sidewalls and the foot of a wall of the surrounding rock
通過屈曲理論分析結果對比表明，彈性屈曲和突變失穩分析的結果比非線性屈曲分析的結果要大得多，非線性分析由於考慮了材料非線性和幾何非線性，因而結果與實際接近實際；當只有初期支護時，隨著地應力的增加，圍巖的荷載分擔率增大，相應地，初期支護的荷載分擔率就減小了；當有初期支護和二次襯砌共同作用時，圍巖的荷載分擔率在50以上，這一分擔率隨地應力的增加其變化不大；支護和巖體的整體分析表明，襯砌底拱及拱腳處應力集中嚴重，隧道巖體側墻及墻角圍巖的應力集中也較大。By adopting the calculating analysis method of elastic - plastic three - dimensional fem numeric simulation, this paper makes a simulation analysis on the structure stability of the shallow cover and unsymmetrically loaded parts in tongyoushan tunnel, mainly simulates the effects caused by different construction orders on surroundings and supporting structure stability, and it centers on the analysis on the weak part, the midwall in the lining of the connecting - arch tunnel
摘要採用彈塑性三維有限元數值模擬計算分析的方法，對桐油山隧道淺埋、偏壓地段結構穩定性進行了模擬分析，主要模擬了不同施工順序對圍巖及支護結構穩定性的影響，重點對連拱隧道整體襯砌中的薄弱環節中墻進行了分析。分享友人
