coarse grained soil 中文意思是什麼
coarse grained soil
解釋
粗粒土-
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
寬級配礫質土是一種粘性粗粒土，是天然土石的混合料，它通常以5mm為界被分為粗料和細料兩部分，顆粒組成是決定寬級配礫質工工程特性的主要因素。 -
Research on affecting factors of rising height of capillary water on coarse grained soil
影響粗粒土毛細水上升高度的因素研究 -
Coarse grained soil is composed of sand and gravel, stone residual, blasted stones etc., which has a characters of less cohesive force among grains and strong ability of water penetration. it is a kind of soil of loose grain structure with better utilization properties in the engineering
粗粒土是指砂礫石、砂卵石、石渣、爆破開採的石料等粗顆粒土石混合料，具有粗顆粒間粘結力小、透水性強的性質，是一種鬆散的顆粒狀結構，具有良好的工程使用性能。 -
Then, using the large - scale coarse grained soil test system, the relative density and direct shear characteristics of sand - gravel mixtures in different size distribution were tested. and the soc affecting mechanism derived from non - uniform granular material was discussed. the phenomenon can be observed that, along with the increase of non - uniform degree, the accumulate structure will become more complex, and the sliding resistance among sands will grow accordingly
在此基礎上，利用大型粗顆粒實驗系統，測定不同非均勻系數沙石材料的相對密度和直剪特性，探討了顆粒非均勻程度對自組織臨界性影響的具體物理力學機制：隨著非均勻度的增大，散粒堆積體的顆粒結構空間分佈堆積方式的多樣性增大，顆粒滑動的摩擦耗能增加。 -
2 the soil is course grained if it contains less than 50 % fines. follow the procedures for identifying coarse - grained soils of section 15
1如果土包含50 %或更多的細粒，它就是細粒土.按照14部分中的程序來鑒別細粒土 -
This article emphasize on further realizing the engineering properties of coarse grained soil through test and research, enabling it to serve the society in a better way
如何通過試驗研究，進一步認識粗粒土的工程性質，更好地服務于土木工程建設是本文研究的重點。 -
This article mainly emphasize on the classification of coarse grained soil from the viewpoint of engineering application ( content of coarse grains ), vibrating method is introduced in the shaping. meanwhile, research is made to the water stability and shear strength. through research, following conclusions are obtained : coarse grained gradation is the main factors to determine its shear strength, when the coarse grains content is over 70 % or around, the maximum shear strength appears : the grains itself have a bigger effect on the shear strength
以往對粗粒土的研究方法多採用擊實法，很少有人研究其抗剪強度特性，本文主要從工程應用的角度（粗粒含量）對粗粒土進行工程分類，成型方法採用振動法，同時對水穩定性、抗剪強度特性進行研究，通過研究得出以下結論：顆粒組成級配特性是決定其抗剪強度的主要因素，當粗粒含量在70左右時，抗剪強度最大；顆粒本身的特性對抗剪強度影響較大，顆粒越堅硬、大小顆粒相差越大、越不均勻、顆粒形狀越呈稜角狀、填築密度越大，抗剪強度就越高；含水量對抗剪強度的影響很小，可以忽略不計。
