| 1. | The engineering property of aeolian sand in inner mongolia 内蒙古自治区风积沙的工程特性 |
| 2. | Pressure - bearing capacity of spread foundation with reinforced aeolian sand 南京地铁软流塑地层浅埋暗挖法施工技术的探讨 |
| 3. | Through the test of sine wave sweep , the character of response of aeolian sand due to motivation is gained 利用正弦波扫频试验,得到风积沙对激励的响应特性。 |
| 4. | Shape characteristics of the natural aeolian sand ripples and their relations with the physical characteristics of surface sand 自然风成沙纹的形态特征及其与地表沙物理性状的关系 |
| 5. | In the paper , through the compaction test , the optimum moisture content and maximal dry density of aeolian sand are determined 本文通过击实试验,确定了风积沙的最佳含水量和最大干密度。 |
| 6. | The aeolian sand is the most abundant material in the desert area , but its engineering property is so bad that it has not been used widely as paving material 风积沙是沙漠地区最为丰富的物质,由于其工程性质较差,目前仍未被广泛用作沙漠地区公路的铺筑材料。 |
| 7. | Through field test and observation , we have achieved the desired results and proved that the using of aeolian sand as paving material is feasible further 同时,本课题铺筑了1公里长的试验路,通过现场检测和观察,进一步验证了风积沙用作沙漠公路路面材料的可靠性。 |
| 8. | On the basis of research of various physical characteristics of coal gangue , fly ash , aeolian sand , through contrast experiment , we chose this new reinforce material 在对煤矸石、粉煤灰和风积砂土的各项物理力学特性进行试验研究的基础上,通过对比试验选择了可供工程应用的新型固化剂。 |
| 9. | As regards sk ( bias angle ) and kg ( kurtosis ) values , the fluvio - lacustrine facies or palaeosols increases considerably compared with the aeolian sands . the former displays positive bias and the latter often approximately symmetrical distribution with only a minority negative bias 就sk和kg变化而言,河湖相或古土壤值较之风成砂明显增高,前者呈正偏,后者常常表现近对称分布,仅少数呈负偏。 |
| 10. | Mz , a , sk , kg and sc / d ( ratio of the sum of silt and clay to sand ) of fluvio - lacustrine , palaeosols and aeolian sands constitute an interlocking , multi - fluctuation process curve with peak and valle y values : the < & value of mz , o and sk values often increase accordingly from aeolian sands to its overlying fluvio - lacustrine facies or / and palaesols , the kg value heightens , too , and the sc / d value also basically consists with its change steps 河湖相和古土壤与风成砂的mz 、 、 sk 、 kg以及sc d (粉砂粘土之和与砂的比值)构成一峰谷交替、犬牙交错的锯齿状多波动过程线:常常是由风成砂至上覆河湖相或和古土壤, mz的值、 、 sk值相应增大, kg相应增高, sc d值亦与之变化步骤基本一致。 |
