| 1. | It ' s also a better kind of permeation proof materials
宽级配砾质土是一种良好的防渗材料。 |
| 2. | The latter is further sub - divided into gravelly and sandy braided fluvial facies
其中辫状河可划分为砾质辫状河和砂质辫状河。 |
| 3. | The gravelly soil is a better kind of damming material . it ' s usually used as impervious core and also as dam shell
砾质上是一种良好的筑坝材料，既能作防渗材料，又能填筑坝壳。 |
| 4. | The dam of mania hydroelectric project is a soil - rock dam with spreading gradation soil of core wall . the height of the dam apices is 4261 . 3m and the maximal height is 76
满拉水利枢纽工程拦河坝为宽级配砾质土心墙土石坝，坝顶高程4261 . 3m ，最大坝高76 . 3m 。 |
| 5. | 3m . as for lack of construction experience in using spreading gradation soil as the permeation proof body in our country at present , the author has studied the soil material carefully
针对目前国内尚没有宽级配砾质土作为高土石坝防渗体的实际施工经验，对土料进行了较为详细的试验研究工作。 |
| 6. | The sahara ' s topographical features include shallow basins , large oasis depressions , serirs or regs ( gravel - covered plains ) , plateaus , mountains , sand sheets , dunes and sand seas ( ergs )
撒哈拉沙漠地形特点包括：浅的盆地、大的萧条的绿洲、砂砾性沙漠或砾质沙漠（碎石覆盖的平原） 、高原、沙席（小沙原） ，沙丘和沙海（砂质沙漠） 。 |
| 7. | The spreading gradation gravelly soil is a kind of clayey coarse - grained soil . it ' s also a soil - rock mixtures . it ' s often divided into fine material and coarse material by the save of 5mm and the granutometric composition affects its project characteristics directly
宽级配砾质土是一种粘性粗粒土，是天然土石的混合料，它通常以5mm为界被分为粗料和细料两部分，颗粒组成是决定宽级配砾质工工程特性的主要因素。 |
| 8. | In this article the conclusion was got from some experiments and researches that the crux of the matter is to solve the seepage stability of the soil and it is possible that gravelly soil is made into impervious core with the protection of filter
但是存在土料的含砾量不均匀、粘粒含量低、渗透系数偏大、天然含水量偏低、塑性较差等缺陷。试验研究还认为，只要解决好渗透稳定问题，做好反滤保护，砾质土作心墙防渗体是可行的。 |
| 9. | The spreading gradation soil analyzed in the article is a cohesive coarse soil . it ' s a kind of crude soil - rook mixtures . it ' s often devided into fine material and coarse material by the save of 5mm and the charge of the two contents affects its project quality directly
本论文研究的宽级配砾质土指的是黏性粗粒土，是一种天然的土石混合料，其颗粒组成通常以5mm为界分为粗料和细料两部分，这两部分组成含量的变化直接影响到它的工程性质。 |
