In this paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.

It is embodied concretely:(1) With the adoption of grouting bolts, the cranny in wall rocks can be blocked up, the air can be isolated, the wall rocks can be prevented to be weatherized and make water, the strength of wall rocks can also be avoided to be lowered;(2) The lax broken wall rocks are commentated to a whole by liquid after they were grouted and the rock"s strength is increased, so the wall rocks become a part of the support structure by using itself and become a whole with the original rock, and the roadway is made to keep stable but not easy to be broken;(3) The spray layer wall are filled with liquid after grouting, the stress is avoided to be concentrated because the load could be evenly acted on the spray layer and the support;(4) The pressure acted on the plank can be delivered to the two sidepieces and then to the bottom by reinforcing the sidepiece; At the same time, the concentration degree of loads acted on the motherboard can be weaken because of the enlargement of the combination arch"s thickness, as result, the rock"s stress is lowered and the heaving is alleviated;(5) The common bolt is made to be fixed the whole length after grouting, the layers are connected to a integral whole and bear the weight of loads, so the support structure"s unity is increased.
具体体现在:(1)采用注浆锚杆注浆,可以利用浆液封堵围岩裂隙,隔绝空气,防止围岩风化,且能防止淋水和渗水,避免围岩被水浸湿而降低围岩的本身强度及造成的巷道变形。(2)注浆后浆液将松散破碎的围岩胶结成整体,提高了岩体强度,实现利用围岩本身作为支护结构的一部分,且与原岩形成一个整体,使巷道保持稳定而不易产生破坏;(3)注浆后使得喷层壁后充填密实,保证荷载能均匀地作用在喷层和支护上,避免出现应力集中点而首先破坏;(4)注浆后使作用在顶板上的压力能有效地传递到两帮,通过对帮的加固,又能把荷载传递到底板;同时由于组合拱厚度的加大,这样又能减小作用在底板上的荷载集中度,从而减小底板岩石中的应力,减轻底臌;(5)注浆加固后能使普通端锚锚杆实现全长锚固,它们共同将多层组合拱连成一体,共同承载,提高了支护结构的整体性。

Even the rocks, which seem to be dumb and dead as they swelter in the sun along the silent shore, thrill with memories of stirring events connected with the lives of my people, and the very dust upon which you now stand responds more lovingly to their footsteps than to yours, because it is rich with the blood of our ancestors and our bare feet are conscious of the sympathetic touch.
岩石貌似麻木、毫无生气,但却在那阳光普照的静悄悄的海岸边淌着汗水,颤栗着回想起那些与我的人民联系在一起的动人往事;那片就在你们脚底下的沙土响应他们脚步比起响应你们脚步来,要带着更多的爱与情,因为它包含着我们祖先的鲜血,而我们赤裸的双足能感觉到它满怀同情的爱抚。

Much of the fascination of Ethiopia lies in its myriad historical sites, the obelisks and stele of Axum, the churches and coptic monasteries in the Tigre, in the Lake Tana isles and in the Lalibela: the African Jerusalem with its monolithic churches46; In Ethiopia there are also nine national parks, two of which include the mountain groups of the Simien and the Bale, while the others lie in the Rift Valley towards Kenya46; The unforeseeable wild landscapes are surely the main attraction of these parks, where many of the animal species are protected, and some of them are endemic to the area46; The proximity of Ethiopia to the Equator and the variety of its habitats make it one of the richest countries in Africa in wild bird life46
埃塞俄比亚这个国家最让人神往的便是它无数的历史古迹,方尖石塔,阿克苏姆石碑,教堂,塔纳湖岛Tigre的科普特人修道院,以及拉利贝拉的非洲耶路撒冷的岩石教堂。在埃塞俄比亚还有9个国家公园,其中两座公园包括塞米恩山和贝尔山山群,其他的则坐落在东非大裂谷接近肯尼亚。一望无际的土地就是这些公园吸引游客的地方,这里有很多被保护的动物物种,其中有些动物是这个地区特有的。埃塞俄比亚靠近赤道,它栖息地的各种各样使得这个国家成为南非野生鸟类最多的国家之一。

The foundation of arch dam usually is layer rock base, and the depths of the layer are small, it is common that several layer rock base contact with one layer element grid. According to the geometry relation and the property of shape function, a new element kind that includes 24 nodes has been proposed to dissect the dam and foundation effectively, whose shape function are independent. In fact the element can be looked as a hexahedron divided into five small hexahedrons. It can be simulate all kind of the condition of the base and the dam.
拱坝的地基一般是层状岩石地基,有的层厚度很小,这样就有多个岩层和坝体某层单元接触,本文根据岩基与坝体接触的几何关系,利用形函数的性质,提出24节点六面体层单元,这种单元实际上是将一个厚的六面体单元分成5个更薄的六面体单元而形成的,其形函数采用可以拆分的形式表达,因此可以方便地解决坝体单元的一、二、三、四个面与错动带接触的情况,可以模拟一、二、三、四个棱边与错动带接触的情况,还可以退化为12节点的四边形面单元,以及五面体层单元。
