water-saturated sand 中文意思是什麼
water-saturated sand
解釋
飽含水砂巖層-
By direct shear for and normal triaxial shear tests of non - saturated desert sand, the parper studied the effect of water content and dry density on the strength of the non - saturated desert sand, and set up the code of this sand. based on the plane strain test of non - saturated desert sand slope, the paper analysed the destruction way of the excavaion side during the construction by means of adding water, and brough forward a formule that calculates the allowable of excavation and pile hole
通過非飽和沙漠砂直剪試驗和常規三軸剪切試驗,研究了含水量和干密度對非飽和砂強度的影響,建立了這種砂的強度準則。通過非飽和沙漠砂邊坡室內平面應變試驗,分析了沙漠井場浸法施工中就基坑壁的破壞方式,推導出了基坑和樁孔容許開挖深度的計算公式。 -
It is pointed out that the compression of water in saturated sand caused by the densification of sand during dynamic loading and the dilation trend of liquefied sand are related to this. a new mechanism of large post - liquefaction deformation of saturated sand is established. according to the mechanism of large post - liquefaction deformation and the reconsolidation volumetric strain formula, a post - liquefaction constitutive model had been put forward
摘要基於大變形機理以及文中提出的再固結體變公式提出了一個飽水砂土液化后本構模型,模型不尋求液化后整個加載過程中的應力應變反應,將液化后過程分成低強度段和強度恢復段兩段來分別進行表達,因為低強度段應變產生於極小的剪應力作用下因此認為該段應變是必然會發生的,強度恢復段應變的大小取決于土體所受剪應力的大小。 -
Two modes have been identified in the earthquake induced damage to soil structures and foundations associated with excess pore water pressure rise in saturated sand
對于在地震中由於飽和砂土的超孔隙水壓力上升而導致的土工構築物和土工基礎的破壞的機理有兩種認識。
