孔直剪
英文
borehole direct shear device-
In this paper, the influence of cycles of drying and wetting on strength and deformation are studied by means of routine direct shear apparatus, triaxial apparatus and light consolidation apparatus which include : the influence of force of constraint on strength, the total stress strength of expansive soils with different saturation degree, the influence of cycles of drying and wetting on the total stress strength, the relation between saturation degree and compression modulus and that between saturation degree and void ratio, the influence of cycles of drying and wetting on the effective stress strength, the relation between saturation degree and generalized suction
本文利用常規直剪儀、三軸儀以及輕便固結儀，分別對非飽和膨脹土的強度和變形特性以及干濕循環對強度和變形的影響進行了一系列的試驗研究。以飽和度、干濕循環次數為變量，分別探求了外力約束對膨脹土強度的影響，不同飽和度膨脹土的總應力強度特性，干濕循環對非飽和膨脹土總應力強度的影響，飽和度與壓縮模量以及孔隙比的關系，干濕循環對飽和膨脹土有效應力強度指標的影響，廣義吸力與飽和度的關系，建議了一組計算非飽和膨脹土變形及強度特性的經驗公式。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。As far as he hollow inclined column - wall transfer r. c joint is concerned, the stress state of transfer beam is very critical, because it bears not only the vertical load transferred from the wall, but also the axial load initiated by the inclined column
對有孔斜柱轉換節點而言，轉換梁的受力最為不利，它不僅承擔由薄壁柱傳來的垂直荷載，而且還承擔由斜柱水平分力引起的軸向拉力，即截面上有彎矩、剪力和軸力的共同作用。
