围岩

The stability of surrounding rock analysis on the underground caverns has been done in the end of this dissertation.

最后本文还对某水电站的地下厂房进行了洞室围岩稳定分析。

Supporting gateway should follow the principle of comprehensive support, the principle of coacting between support and surrounding rocks, and the principle of control and temporary strengthening support.

回采巷道的支护应充分遵循综合支护原则，支护与围岩共同作用原则，控制原则以及短期临时加强支护的原则。

At first, mineral composition and distributing of impurities in andalusite grains were studied by SEM and EDS. The results showed that main mineral impurities were biotite, ilmenite, clay species, the wall rock conglutinated at brim of andalusite and impurities in the chiastolitic cruciform pattern were easily removed, but the small impurities in andalusite grain were hardly removed.

首先，利用SEM和EDS分析了红柱石矿的矿物组成和杂质分布，结果显示这种红柱石矿所含的杂质矿物主要是黑云母、钛铁矿和黏土矿物等，其中分布在红柱石颗粒边缘的围岩和空晶石内的黑十字容易去除，而分布在晶内的细粒杂质则不易去除。

The finite difference software FLAC3D for Fast Lagrangian Analysis of Continua was applied to study and analyze the deformation and damage process of surrounding rock.

通过有限差分方法FLAC(上标 3D对围岩变形、破坏过程进行分析研究。

Organic carbon may be released from the host rocks and dissolved in the hydrothermal solution during the thermal maturation and de-carbon process of the organic matter. Hydrogen and oxygen isotope studies reveal that the upward ore forming fluid is gernerated via mixing of magmatic water and convecting groundwater.

矿床中的碳具有岩浆源碳与有机碳混合的碳同位素组成，其中的有机碳可能来源于容矿围岩中有机质热演化过程中的去碳作用。

The concentrations of metal elements in Jinji formation outside the mining area is similar to or lower than the averages in sedimentary rocks all over the world. This fact challenges the argument that the metals in Sungxi Ag-Sb deposit is mainly from Jinji formation and is similar to the elemental distribution around an epithermal deposit where ore forming metals are leached by convecting solution.

在区域上，该层位地层中的成矿元素含量与沉积岩中的平均含量相近偏低，而矿区地层中的成矿元素含量很高，表明矿化作用大大升高了成矿元素在矿区围岩中的含量，嵩溪银锑矿床不大可能是海底火山喷流-沉积或喷流沉积-改造矿床，而具有浅成低温热液矿床的成矿元素分布特征。

The electromagnetic wave CT technology has been proved to be an effective tool for detecting hidden defects in dykes and dams.

电磁波CT技术是CT技术的一种，它对探测钻孔之间及其旁侧与围岩有较大高

In the simulation model, the cellular automata model was applied to describe the tunnel network system, a methane gas cell was used to represent an energy unit of methane gas which was eradiated from walls of working spaces, mined coal piles, surrounding rocks and excavations, a grid cell was used to represent a tunnel grid and its states, these grid cells contain such state parameters as velocity and quantity of methane gas.

在该方法中，用元胞自动机模型描述地下矿巷道网络系统，用瓦斯元胞来描述从工作面煤壁、采落的煤堆、围岩和采空区渗出的瓦斯能量单元；用格子元胞描述巷道格子及其状态，这些格子元胞均用瓦斯运移速度和瓦斯含量等状态参数来描述。

The variation of structural characteristics for excavated tunnels was studied.

研究了黄土隧道开挖后围岩结构性的变化规律。

D depth-averaged model for flows in river with submerged groins;2. Simulation study of organ pipe nozzle submerged water jet;3. The submerged tunnel is simulated by the Elastic-Plastic FEM to analyse its influence on the environment.

为了分析淹没坑道对环境的影响，采用弹塑性有限元法对被淹没的坑道进行了数值计算，分析了不同情况坑道衬砌及围岩的破坏变形情况，同时提出了相应的加固方案，并对拟采用的不同方案加固效果进行了模拟分析，分析结果表明所提出的加固方案可行。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
