膨胀土地区的坡地建筑设计是急待解决的课题。为此,从1973年至1982年,在我国8个省15个地区,对膨胀土斜坡和临坡建筑物进行了长期的现场实测和相应的室内外试验。在此基础上,重点解剖了93个膨胀土边坡和120余栋有代表性的临坡建筑。本文是此项研究工作的总结.它包括:(1)膨胀土边坡土体的运动规律及膨胀土斜坡稳定性的评价方法;(2)我国膨胀土地区的自然稳定坡角值和局部边坡的容许坡比值;(3)坡地膨胀土地基的特殊性及其对建筑物变形的影响,各种处理措施的效果及其适用范围;(4)临坡建筑设计的原则及其处理措施。
Slope land architecture design in expansive soil area is an urgent issue to be solved. For this reason, from 1973 to 1982, in the 15 regions of 8 provinces in China, long-term on-site measurements and corresponding indoor and outdoor tests were carried out on expansive soil slopes and on-slope buildings. On this basis, we focused on dissecting 93 expansive soil slopes and more than 120 representative facade buildings. This article is a summary of this research work. It includes: (1) the movement law of expansive soil slopes and the evaluation method of slope stability of expansive soils; (2) the natural slope angle and local edge of expansive soils in China. (3) The particularity of the sloping ground expansion base and its effect on the deformation of the building, the effect of various treatment measures and the scope of application; (4) The principles of slope building design and its treatment measures.
