冲积层

The upper layer is modern river deposit; the middle layer is relative thick,mainly consisting of icewater deposit,colluvial deposit and deluvium as well as barrier dam accumulation; the bottom layer is formed by ancient river bed deposit and boulder rocks.

河谷覆盖层是由一套不同时期、不同成因类型的沉积物相互迭置的结果，由表及里宏观上可分为3层：表层为现代河流相堆积；中间主要为以冰水、崩积、坡积、堰塞堆积与冲积混合为主的加积层，厚度相对较大；底部主要为古河床的冲积、冰水漂卵砾石层。

This paper focuses on some of the special technical features to be considered in the design of pile foundations, including effects of particular site conditions, pile group effect s, lateral resistance of pile cap and flow slide of liquefiable soil etc.

主要说明台湾高速铁路工程南部段自里程TK188至TK343长约155km松软冲积层中桩基础设计中几个需详细考虑的因素特殊地盘效应、群桩效应、桩帽侧向阻抗及土壤液化地层滑移等。

According to calculations, it was necessary to adopt a new type of structure of the shaft lining with vertically yieldable segments for reason of safety.

分析计算表明：应采用竖向可缩新型井壁结构防止井壁因冲积层疏排水而破坏。

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.

利用大型竖井模拟试验台，对冲积层疏排水过程中立井井壁受到的竖直附加力的变化规律开展了模拟试验研究。

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。

The Yao' an station was installed on the Quaternary allurium in the Yao' an basin and has a site amplification factor of 3 to 4 for S-waves and that of 6 to 7 for coda relative to the rock reference station Pila in the frequency range of 3 to 6 Hz.

姚安台位于姚安盆地第四系冲积层上，对应苤拉基岩台，在3~6Hz低频段S波有3~4倍的放大因子，尾波有6~7倍的放大因子。

Lanyang Plain is covered by the Holocene alluvium of the Quaternary Period, which is relatively young in geological age, with various thicknesses of soil layers. The soft soil layers are easily to be compressd under construction loading and subsequently cause the settlement problems.

兰阳平原为第四纪全新世冲积层所覆盖，地质年代轻，土层厚度深浅不一，其组织质地较疏松软弱，易受外力影响而发生地层压缩，进而形成地层之垂直变位等问题。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
