coarse-grained soil
解釋
粗顆粒土壤-
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。
