工程實踐證明，節理巖體高邊坡的穩定性取決于邊坡中的不連續結構面，如節理、裂隙、軟弱面和不同巖層的分界面，這類結構面的存在使巖體變形破壞的特性與完整巖石截然不同，因此，有必要加強對節理巖體高邊坡變形破壞機制的研究及相應的節理巖體高邊坡穩定性評價方法的研究。In order to obtain a precise description to the joint persistence ration, the author define two types of persistence ration according to different methods of measuring and statistics

節理巖體熱應力問題的非連續變形分析方法One is the " belt persistence ", which is defined as the total length of joints teace length in a 1m wide belt projected to a basic line ( eliminating the overlay section ) over the length of the basic line. another is the one called as " search persistence ", which is defined a as the total length of joints trace length on the searched potential slipe surface over the length of the slip surface. thus, the author establishes a measuring and calculation system to these definitions and finishes a great deal of field investigation aiming at the joints trace length and the " rock bridge " survey
在此基礎上，針對a區邊坡的穩定性，結合邊坡的破壞失穩模式，以邊坡節理巖體的連通特性的研究為突破點，從節理巖體的幾何參數的統計分析出發，採用monte - carlo隨機模擬原理形成節理網路模擬圖，以巖橋和節理組合破壞的內在機制為依據，以搜索節理巖橋組合的最短路徑為手段，通過帶寬投影法與路徑搜索法兩種方法的計算，獲得了sn向中緩節理的連通率分別為48 . 7和56 . 78 ，最終推薦60的連通率進行了邊坡的穩定性分析與計算，並結合工程實際，計算了邊坡的推力與錨固力，最終為邊坡的支護設計提供優化建議。One of distinct characters of geotechnical problems is that there exist various interfaces such as interface between the structure and geotechncal medi8, the joints in rock mass, sliding face in soi1 and so on, which will effect the mecbocal behaviors of the geotecndcal media and the structures significanly so far though the finite element method has been wildly used in geotecbocal field, it still remains an inthectable problem to simulate these inteffoces idealiy in the numerical analysis
計算對象的不連續性是巖土工程問題的一個重要特點，這些不連續面主要是存在於基礎?土體、擋土結構?土體、地下結構?圍巖等結構與周圍巖土介質問的界面，或是巖體中的節理或軟弱夾層、土（巖）滑坡的滑動面等。不連續面的存在顯然對結構及巖土體的受力變形有著不可忽略的影響，因此在計算中不應無視它的存在。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。At first it analyzes the bedding rock slope ' s bedded rock and its incontinuity face, and studies the stress, strain, stability ' s condition of the bedding rock slope, fully considering the cohesive force of rock layer and incontinuity face. geologic mechanics models of two types of bedding rock slope are set up, the instability coefficient of bedding rock slope under different mechanical parameters is computed, and the conclusion that the stability of bedding rock slope is relation to rock layerer, cohesive force of incontinuity face, inner friction angle and rock layer obliquity has been gotten. based on the above discussion, the thesis comes down the influence of rock layer and the incontinuity face on the bedding rock slope to incontinuity face ' s influence factors, and discusses other factors that influence the bedding rock slope ' s stability, so gains the evaluating and forecasting index marks
本文首先對順層邊坡的層狀巖體及其中的層理面和不連續面進行了分析，對其應力應變進行了研究，得出了順層邊坡的穩定性不僅與巖體中巖石的強度有關，還與巖體中層理面及不連續面的內聚力、內摩擦角及其傾角有關；論文建立了層理面和節理面的地質力學模型，討論了其力學參數變化對邊坡穩定性的影響，並在此基礎上將層理面和節理面歸納為順層邊坡穩定性的結構面影響因素，同時討論了影響順層邊坡穩定性的其他因素，從而得出順層邊坡穩定性的評價預測指標。Although various mechanics models have put forward many numerical techniques, the widely used one that is commonly admitted by engineers is the finite element method. combined the joint elements, on some extent this method could overcome structural surface obstacles described by the mechanics of continuous media such as the joint of canny existing in the inner of rocks. until now, the finite element method has been widely employed because of the mature of the large - scale construction computing software
針對各種力學模型提出了多種數值方法，最廣泛使用的並獲得了工程界普遍承認的是有限元法，有限元法結合節理單元可以一定程度上克服連續介質力學在描述巖體內部存在節理裂隙等結構面的障礙，目前有限元法由於大規模結構計算軟體的成熟而為工程界所普遍運用。分享友人
