( 3 ) ensemble character of structural planes as follows : in left dam abutment, meta basalt schistosity is main, and the structure is clockwise. low dip angle jointing did n ' t develop in rock mass ; in right dam abutment, rupture and jointing structural plane is main, and the structure is reversed. the structure was of obvious macroscopical slaty character
( 3 )通過對上述結構面的分析,得出其總體特徵為:左壩肩以變玄武巖片理為主體,呈順向結構,巖體內緩傾角節理極不發育;右壩肩主要為斷裂及節理型結構面,呈反向結構,且具有明顯的宏觀板狀結構特徵,並發育有一定厚度的構造軟巖帶。We deduce that it is a relic old crust that was brought upwards during the formation of neo - tethyan ophiolite. the step heating 40ar - ' 9ar spectra show that during 100ma, luobusha ophiolite suffered intensely alternation, which affected distinctly the k - ar system ; during 771ma some basalt formed in the country rock of xiubugabu ophiolite ; during 55ma, the pillow basalt of rikangba ophiolite affected by a strong thermal event ; all the variety of ages illustrates possible impacts of the subduction - collision between india and eurasia. through dissecting mainly the gabbro of luobusa ophiolite and studying the 40ar / 39ar
~ ( 40 ) ar ~ ( 39 ) ar階段升溫年齡圖譜顯示, 100ma左右羅布莎巖體經歷了較強的後期蝕變作用,對其k ? ar體系造成明顯影響; 77 1ma休古嘎布巖體圍巖中形成玄武質火山集塊巖; 55ma日康巴巖體巖石枕狀玄武巖受到較強熱事件影響;這些~ ( 40 ) ar - ~ ( 39 ) ar年齡上的變化顯示了印度板塊與歐亞板塊俯沖?碰撞對該區的強烈影響。After excavation, there are concentration phenomenon of stress at the corner or the shiplock room, and the tension zone lies in half of the middle part as well as the part of the two slopes to the lower part of the upright wall. finally the analysis results are compared with site monitoring data in period of construction as well as the feedback reports, the result of all comes to meet with each other very well
開挖完成後,在閘室拐角處存在不同程度的應力集中現象,中隔墩上部1 2的巖體及南北邊坡至直立墻頂部平臺以下的部分巖體為拉應力區。在兩側邊坡及邊墻的塑性區出現在損傷區和部分卸荷影響區內,中隔墩大部分區域的巖體都進入了塑性狀態,閘室底板處的塑性區基本上與損傷區一致。The results of the experiments indicate that : thermal plumes in the mantle ( i. e. mantle plumes ) should be divided into two types, vertical plumes, as mentioned traditionally, and non - vertical plumes, including those of inclined - columns, vortexes, etc., and the former may be only a particular case of the latter ; under the condition of the coriolis force to be ignored
在忽略科里奧利力的情況下,板塊的下插和滯積下沉、巖石圈根的存在以及地幔介質粘度的非均勻分佈等都可能構成不同形狀的障礙導流體,導致地幔的渦旋運動。At first, the mechanical model of joint is discussed, and the constitutive relation of the rough joint, especially the bolt - supported joint, is given. then bedding slide of bedding stratified rock slope is studied adopting limit equilibrium method, and a formula of stability is brought forward. at last, the bedding stratified rock slope ' s buckling deformation and failure mechanism and its evaluating method of stability is investigated, a corresponding mechanics model is established, then detail research to this failure mode is made in theory combining the energy law and elastic stability theory of plate and beam, and an analytical solution of the yielding curve is educed from this model
文中首先對結構面的力學模型進行了一定的探討,提出了粗糙結構面尤其是加錨結構面的本構關系;然後採用極限平衡法,研究了順向層狀巖質邊坡的順層滑動失穩,提出了其穩定性計算公式;最後,結合能量定律和彈性板梁穩定理論,探討了工程中常見的順向層狀巖體邊坡潰屈失穩時的破壞機理、變形規律和穩定性定量評價方法,建立了相應的力學模型,求出了其相應的解析解,並提出了臨界坡長與最大彎曲位置的確定方法。Firstly the paper introduces and generalizes the distribution, engineering classification and engineering properties of the tertiary mudstone in guangxi. then the paper analyzes the pile - tip bearing behaviour of the tertiary mudstone in guangxi. last aiming at the tertiary mudstone in nanning basin, the paper studies on its bearing capacity of pile tip by methods of in situ plate loading test, rigid - plastic body theory and elasto - plasticity theory
本文首先歸納介紹了廣西第三系泥巖的分佈、工程分類與物理力學特性,分析了廣西第三系泥巖的樁端承載性狀,然後以南寧盆地第三系泥巖為代表,採用原位載荷板試驗、剛塑體理論及彈塑性理論三種方法研究其樁端承載力。分享友人
