查询词典 alluvium

China, in its headlong attempts to modernize, has often demonstrated a dismayingly cavalier attitude toward the well-being of its people: skyscrapers are built with little attention to safety standards and are invariably far from earthquake-resistant; huge dams ― not least the monstrosity that has so ruined the Three Gorges of the Yangtze ― are erected in a slapdash fashion; subways, like the system burrowing through the waterlogged alluvium beneath Shanghai, are built with incautious haste; freeway tunnels are bored through earthquake fault zones.

呼唤现代化的中国往往对民众的福祉展现出惊人轻慢的态度：摩天大楼的建造很少注意安全标准，远远不能抗震；巨大的水坝仓促落成；地铁的建造也是不谨慎的匆忙，例如穿过积水冲积层上海地铁系统；高速公路隧道的钻孔经过地震断裂带。

But the strata with high ground water level are composed of alluvium clays、 silty clay、 gravels and crushed stone soils in Chengdu;And the shield will drive in the interzone with complicated geologic environment, especially in the strata contained more than 50 percent of gravels which diameter is greater than 5cm, also contained big grain size gravels(the maximum diameter is about 1m)、 cement gravels and silty sand with lentoid mass;And on the ground there have many serried buildings in the prosperous zone.

而成都地铁工程将主要穿越由冲积粘性土、粉土、砂砾和碎石类土组成的覆盖层，地下水位高，盾构将通过大量地质条件和环境条件均极为复杂的区间，特别是地层中还夹杂有大漂石、胶结砾石层、粉细砂透镜体，隧道围岩中直径大于5cm的砾石含量一般都在50%以上，最大的漂石直径达1m左右，且地面多为建筑物密集的繁华地区，施工难度大，国内尚无先例，在国外也无完全成熟的经验。

The simulation test s were carried out to study the variation of the vertical additional force acted on shaft lining by surrounding soils during dewatering of alluvium by means of multi-function rig in vertical shaft.

Engineering geological structure classification is divided into macro-, fine-, and microstructure. Macro-structures include alluvium predominated structure, multiple-binary-rhythm structure, thick boulder and gravel structure, saccate buried valley structure and tremendous composite structure, fine structures homogeneous structure, stuffed structure, porphyro-structure, and space frame structure, microstructures cemented, semi-cemented and loose texture.

利用第四纪构造与气候环境演变控制论的观点，在成因分类的基础上，对覆盖层进行了结构工程分类，按沉积相的不同组合特点分为冲积为主的结构、多重二元韵律结构、厚层漂卵石层结构、囊状槽谷结构、巨厚复合加积结构等五种类型；按颗粒组成和结合状态，分为均匀型、充填接触型、斑状型和架空型四种细观结构；按胶结成岩状态分为胶结、半胶结和松散三种微观结构。

In order to ascertain a reasonable strip mining project for the coal mining under villages with thin bedrocks under the thick alluvium in Linhuan, the characters of surface subsidence in strip mining were studied by numerical simulation method based on discrete element.

为了确定临涣煤矿厚表土层薄基岩下合理的村庄压煤条带开采方案，采用离散元数值模拟方法研究厚表土层薄基岩下条带开采地表沉陷特征。

The assessment result shows: the infirm zone of the aquifer basically distributes in the limestone area of low Ordovician -top Cambrian, which the cranny is uncovered and overgrown, the area is also the direct recharge area of spring basin. In addition , in the rivers valley area of Jin xiuchuan and Bei sha river, because the leakage of the river is serious, the contamination can leak easily to the groundwater in the area of surface and near the river, so this area also is the infirm zone. Frail zone distributes in the uncovered area of mid-Cambrian which the canny upgrowth is commonly, parts of the zone distributes the relatively impervious layer such as shale. In the north-west area where is the down-rivers of two rivers, the alluvium is thick, the protection to the limestone is good.

评价结果显示，济南岩溶泉域含水层很脆弱区基本分布在济南泉域的岩溶裂隙非常发育的、裸露的下奥陶～上寒武的石灰岩地区，该地区也是泉域的直接补给区，另外在锦绣川、北沙河等河谷地带，由于河床渗漏严重，地表水及近河地带污染物容易渗入地下，也为很脆弱区；脆弱区一般分布在裸露的中寒武地层区，岩溶裂隙发育一般，部分地带分布有页岩等相对隔水层；西北部两河下游冲积层较厚，对下伏石灰岩保护功能较强，属于脆弱性相对很低区。
