1·Pulverized coal ash is hydraulically filled on ground of Zishan. Its grains were fine as silty sand.

紫山灰场粉煤灰作为一种冲填土，粒度细，似粉砂。

2·Because of the high dry density the dynamical strength of silty sand is higher than those of ordinary sands.

试验得到粉砂的动强度高于一般砂性土，主要是因为制样控制干密度比较大。

3·This technology is significant to improve oil production from unconsolidated silty sand stone reservoir and to the field applications.

粉细砂岩油藏防砂工艺技术对于提高疏松砂岩粉细砂油藏产能及现场应用有重要的指导意义。

4·The finer layers generally consist of carbonaceous clay, mild clay and silty sand, showing characteristics of lacustrine sedimentation.

细粒层均为含炭的粘土、亚粘土和粉砂，具湖塘相沉积的特点。

5·In this paper, the case studies of two tall buildings built on silty sand improved by vibro - replacement stone column in Hangzhou are reported.

本文介绍杭州两座高层建筑物采用振冲碎石桩加固粉砂土地基的工程实例。

6·The consolidated silt is found in silty sand coast, river mouth etc., which brings lots of engineering problems, which make it necessary to research on.

我国粉沙质海岸、河口地区等区域常有铁板沙出现，带来许多工程问题，开展相关问题的研究十分必要。

7·Earthquakes have to be taken into account. They can make landslide more possible. If the foundation is made of silty sand, liquidified damage is more possible.

在地震区筑坝，还应考虑地震影响。地震的作用增加坝坡坍滑的可能性。粉沙地基在强烈振动作用下还容易引起液化破坏。

8·We also discover the Lower Quaternary limit locates in M/G boundary or the interface between the grey-green clay-silty sand layer and brown-red silty clay sand layer.

研究表明第四纪下界存在于该剖面的灰绿色粘土粉砂质砂层与红褐色粉砂粘土质砂层之间（即M／G面上）。

9·The earth dam foundation at Heilongtan Reservoir in Lunan county, Yunnan province is consisted of silty sand Layer and silty soil with low bearing capacity and poor shear strength.

云南省路南县黑龙潭水库土坝基础属粉细沙层及低液限粉质土，允许承载力低，抗剪强度差，不足以维持坝体稳定。

10·The aeolian silty sand in shale can provide good guide to study of paleoclimate about lacustrine shale and varve, and to reconstruct sedimentary environment of paleolake accurately.

页岩中风成粉砂沉积的发现，可以进一步为研究有关湖相页岩和第四纪纹泥的古气候变化、正确恢复古湖泊沉积环境提供良好的指标。
