1·According to the useful requirements and bearing characteristics, the spacial effects of debris flow gravity dam at the narrow gully section were full analysed with finite element method.

本文根据泥石流重力坝的使用要求与受力特性，用有限无法对建于狭窄河谷泥石流重力坝的空间效应作了较为详细的分析。

2·The check dam is one of the most effective structures to control the debris flow in the original area.

谷坊正是能够在泥石流形成区对泥石流灾害进行有效防治的工程措施之一。

3·Masonry-gravity dam, build at the narrow gully section of the small or very small basins, is a kind of retaining works of debris flow in common use.

圬工重力坝是泥石流工程防治常用的一种坝型，多建于特小流域或小流域沟谷的狭窄地段。

4·The official, Chen Lei, was quoted as saying that the unusually large amount of debris near the dam also could damage boats nearby and hurt water quality. Mr.

这名官员名叫陈磊，报导引述他的话说，大坝附近反常的大量漂浮物还可能毁坏周边船只及损害水质。

5·The integrity of the structures was questionable, both because of their age and because the Elwha Dam breached during construction and was patched with fill and debris.

大坝结构也遭到质疑，一是因为其年代久远，二是因为它在建造过程中就出现垮塌，后来又用废料和残片填补。

6·Debris bam was added to the model to simulate the impulse force of debris flow to the dam and the variety of debris flow field after adding the dam based on the cleuch 3D land form model.

本次研究在建立沟谷模型的基础上，加入拦挡坝模拟了泥石流对坝体的冲击力及泥石流流场受坝体拦挡之后的变化情况。

7·Tailing pond is an artificial debris flow hazard with high potential energy, so it is very important to monitor its stability to prevent the occurrence of dam breaking.

尾矿库作为一种高势能人造泥石流危险源，其稳定性的监测对防止溃坝灾害的发生起到至关重要的作用。

8·Sandstone, mudstone and limestone rock-debris have a very wide distribution and are very frequently used as dam materials in Sichuan Provi- nce.

砂岩、泥岩和灰岩石碴料是四川省分布广，使用最多的几种坝料。
