bedding plant

Stability of rock slopes is generally controlled by the structure of rock masses , especially the soft structure surfaces . analysis of rock mass structures is a key to establish geological models and numerical simulation and a foundation to assess the stability of rock slopes . the weak structure surfaces are mainly bedding planes , faults , joints , schistosity plane and contact zones of intrusive bodies . since they are different in genesis and scale , the rock masses are different in features and mechanical intensities . based on the combination of rock structure bodies , 15 basic modes of deformation and failure of rock slope are systematically summarized . the deformation and failure of rock masses actually result from the recombination and rearrangement of these rock bodies . there are 11 types of rock mass structures and various deformation and failure of bank slopes are present in the reservoir area of the three gorge project 巖體結構,特別是軟弱結構面對基巖斜坡變形與破壞具有顯著的控制作用,巖體結構模式分析是建立斜坡地質模型和數學模型的關鍵和評價斜坡穩定性的基礎。巖層層面斷裂構造節理裂隙片理與劈理以及侵入體和圍巖的接觸帶等是控制基巖斜坡穩定的軟弱結構面,這些成因不同大小不一的結構面將巖體分割成性質各異力學強度不均的各種巖體結構體,構成了15種基巖斜坡變形破壞的巖體結構基本模式。不同結構體的重新組合與排列是斜坡失穩的內在原因。

The above analysis shows some results as follows : generally the discontinuities including bedding planes are favor to the stability of slope , which means that most of the slopes will not suffer large sliding failure ; most of the high slopes situated in the interest area are stable . however there are some potential unstable wedges which can be identified based on the key block theory ; some suggestions for reinforcing high slope are presented based on the stability analysis and environmental friendly consideration 結果表明:該區邊坡巖體條件對邊坡整體穩定性有利;區內高陡邊坡以穩定及基本穩定為主,不穩定邊坡較少,但潛在局部不穩定塊體較多;依據邊坡的工程地質特征及穩定性評價結果,對該區高陡邊坡的防治提出了建議。

And rock triaxial serve testing system is used , through model test involving bedded planes and a set of joint normal to the bedded planes in rock mass , multiple sliding failure affected by properties of joints and confining pressure is analysed , the condition triggering multiple sliding failure and characteristics of failure plane are given , under the co - action of inclination of connective joints ( bedded planes ) , interlocking conditions of critical joints and confining pressure 并在室內利用巖石三軸剛性伺服機,通過模型試驗對巖體的層面和一組與層面正交的節理的情況進行模擬研究,分析了結構面性狀和圍壓對復合式滑移破壞的影響,給出了在貫通性結構面(層面)傾角、非貫通性結構面以及圍壓等因素共同作用下,節理化巖體發生復合式滑移破壞的條件以及破壞面特徵。

According to specificities for jointed rock mass , multiple sliding failure of a jointed rock mass is presented , due to accumulation of stress along bedded plane of rock mass and destruction of remnant intact rock bridges between bedded planes and joints 摘要針對節理化巖體的自身特點,提出沿巖體層面產生的應力集中以及層面與節理之間的殘馀完整巖橋破壞,將可能導致巖體產生復合式滑移破壞。

When the rock mass of dam abutment is enclosed by faults , joint fissures and bedding planes , it is necessary to carry out holistic anti - slide stability analysis in order to make the abutment withstand potential slide 摘要當拱? ?肩巖體為斷層、節理裂隙、層面等結構面所圍成,有可能產生滑移時,就應進行整體抗滑穩定分析。

On this basis , from the enterprise microseism bedding plane , it develops and gives the synthetically study frame about resource , ability , surround environment and compete superiority 在此基礎上,從企業的微觀層面,推演給出資源、能力、外部環境、競爭優勢整合研究框架。
