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製作用，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。After researching the loads on dangerous rock synthetically, the author points out the development and collapse mechanism of dangerous rock : the geology foundations that forms dangerous rock are the constructional surfaces such as tectonic fracture 、 relief fissure, soft interlayer etc. the developing of dangerous rock is due to release of in - situ stress in rock 、 aeolation 、 water erosion and root flerry. the main loads leading to collapse of dangerous rock are gravity, water pressure and earthquake force
在綜合研究危巖上的各種作用之後，本文提出了危巖的形成和破壞機理：硬質巖體中構造裂隙、卸荷裂隙、及各種軟弱夾層，結構面的的存在是危巖形成的地質基礎；地應力卸荷、風化、流水侵蝕、植物根劈是危巖發育的主要作用；重力、水壓力、地震力是危巖崩塌的主要荷載。Abstract : the effects of airfoil geometric parameters on wing " s spacial and polarized scattering characteristics have been systematically revealed. the results of the study indicated that the calculating value of diffraction from trailing edge by using the formula of the straight wedge is very far from experimental results for vertical polarization, and the contribution of thickness of the trailing edge to scattering must be considered in the calculation. the scattering peak of leading edge depends only on radius of airfoil for horizontal polarization. but for vertical polarization, it depends on maximum thickness and the location of maximum thickness. engineering formulas for evaluating all scattering peaks were given in the paper. it is important for the design of low - rcs wing
文摘:系統地揭示了翼形幾何參數對機翼的空間散射特性、極化散射特性的影響規律.研究發現，在垂直極化狀態下用理論尖劈公式計算機翼后緣繞射的計算結果與實驗結果相差甚遠.提出在垂直極化狀態下機翼后緣繞射的計算必須將后緣厚度考慮在內的見解.對於水平極化，前緣散射波峰只與前緣半徑有關；而對於垂直極化，前緣散射波峰與翼形最大厚度以及最大厚度位置有關.給出前後緣散射波峰的工程估算公式，為低雷達散射截面（ rcs ）機翼設計提供依據The anatomy of small - scale to meso - scale deformational structures have resulted in the reconstruction of the structural framework of the yanbian group. the statistical analyses of the fold hinge and cleavages developed in the yanbian group suggest the trend of the first stage penetrating structures of the yanbian group is een - wws. 2
基於對鹽邊群中、小尺度變形構造進行構造解析，建立了區域構造格架，通過對褶皺樞紐和劈理的分析，提出鹽邊群第一期透入性變形構造的走向為北東東?南西西向。Among them, the uncompetent pelitic series are cleaved in the srong - deformation zone with relatively high temperature, high pressure ; with weak hydrofracturing, the competent sodium - rich series dilatacying and forming microfracture ( ie, embryonic fracture ) in the core of the weak - deformation demain, which is a natural lens - like pumping centre with relatively low temperature, low pressure and high permeability
強變形帶中的非能幹性泥質巖系強烈劈理化，為相對高溫高壓帶；弱變形域內的能幹性鈉質巖系則伴隨弱水力壓裂作用發生擴容，形成雛形斷裂的微裂隙，同時，它是一個相對低溫、低壓、高滲透率的透鏡狀天然泵吸中心。The technique of splitting grouting is a method for handling the earth dam " s stability with deformation and permeation. it is developed quickly in several decades. the author, regarding left subsidiary dam of shenzhen reservoir as an example, uses the limited element method to proceed the dam ' s seepage calculation, combines the contrast analysis with prototype data and predicted data, then compares the dam ' s seepage behavior " s changes before splitting grouting with that after splitting grouting, has some basic conclusions
土壩壩體劈裂灌漿技術是近幾十年來發展迅速的一種處理土壩壩體變形穩定和滲透穩定問題的方法，本文以深圳水庫左副壩為具體實例，利用有限單元法進行了壩體滲流計算，並與原型觀測資料進行對比分析，然後比較了劈裂灌漿前後壩體滲流狀況的改變，並對壩坡穩定進行分析，得出了一些基本結論，對利用有限單元法求解劈裂灌漿前後壩體的滲流問題提出了一些建議。分享友人
