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 grav

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 results show that when the depth gradually reduces, pH values gradually increase, but conductivities and (superscript – subscript 3) content gradually reduce. There are also obvious differences between the groundwater in loess, alluvial deposit and acidity rock in the south of Chang'an, which relates to the depth, the characters of loess, the lixiviation and the evaporation. The element content of groundwater is high in the loess tableland, so it's fitter for drinking than the groundwater in the Cuihua mountains, which is of acidity and low element content.

结果表明，长安南部黄土塬随着层位的降低，pH值有逐渐增大趋势，电导率和HCO(上标–下标 3)含量有逐渐减少的趋势；黄土地下水、冲积层地下水和酸性岩石地下水的化学成分存在明显差异，这与其理深、地层性质、溶滤与蒸发作用不同有关；长安南部少陵源黄土地下水元素含量较高，比呈酸性、元素含量低的翠华山泉水更适于饮用。

In order to accurately calculate the mining induced subsidence in thick alluvium areas so as to decrease the mining damage and environment disruption,the calculation of surface subsidence caused by water loss of clay was discussed based on probability integral method and used in a real case.

为了更加精确地计算厚冲积层矿区的煤矿开采沉陷问题，减小采动损害与环境破坏，基于煤矿开采沉陷计算的概率积分法，探讨了由于黏土体失水引起的地表沉陷计算问题，推导了黏土体失水引起的地表下沉计算公式，并应用于煤矿实际地表沉陷，加以分析论证。

A soil wind erosion experimental plot was set up in the alluvial sandy land of old yellow river,which is in Xiajin County of Shandong Province,and the soil wind erosion quantity was tested with measuring scale method in the observation farmland shelter-forest network and the comparison place.

在山东省夏津县黄河故道冲积沙地建立土壤风蚀试验区，采用标尺法对3种网格的农田防护林和对照地的土壤风蚀量进行观测，测定结果表明：农田防护林网可明显减少风蚀损失，其中，130m×300m林网相对于对照减少土壤风蚀量81%，260m×300m林网相对于对照减少78%，300m×400m林网相对于对照减少75%，即随着网格面积的增加对风蚀量的影响越来越小。

The primary ore of tin, most sources of Cassiterite today are not primary deposits but alluvial deposits containing weathered grains.

锡原生矿以及今天我们所见到的锡石的大多数出产地其实都不是她的原生矿藏，真正的锡石原生矿是那些含有风蚀晶粒的冲积层矿床。

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。

Because of its variety and lack of transgressive condensed section or coal bed, uniform mode of fluvial-alluvial sequence stratigraphy has not been concluded after twenty years application.

由于河流-冲积相沉积的多变性和缺少湖侵形成的密集段或煤层，其层序地层的研究经过多年的发展和应用，仍然没有统一的模式。

Five pieces of paleogeographic maps were made out with modern stratigraphic principles and sedimantary system method. It is shown by the maps that in the beginning of the Changzhougou time the Yanshan Region was occupied by alluvial environment with paleoriver flowing northeast, in the middle of the Changzhougou time a transgression changed whole Yanshan Region into shoreline-shallow sea environment gradually, and sedimentary boundary extended so continuously that by the Gaoyuzhuang time it had overpassed far beyond the Yanshan Region.

在缺乏良好等时面的情况下，本文依据现代地层学原理和沉积体系分析法编制了常州沟组初期与中期，串岭沟组初期，大红峪组初期，及高于庄组初期燕山地区的岩相古地理图，示意了燕山地区在长城纪时由冲积扇-河流为主的陆地环境向滨海-浅海环境的演变过程，并揭示了沉积区域不断扩大的趋势，表明常州沟组初期，以蓟县-宽城为轴线发育了冲积相组，海岸线可能在燕山以北，常州沟组中期发生海侵，沉积区扩大至整个燕山地区，大红峪组时海盆范围继续扩大，高于庄组时，沉积边界已远远超出燕山地区。

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。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
