摘要
将加筋材料假定为作用于路堤堤底的水平均布作用力,采用极坐标体系下的Flamant和Cerruti公式和统一强度理论,推导了考虑加筋及中间主应力的地基临塑荷载与临界荷载公式,提出了考虑堤底水平加筋下路堤临界填土高度计算方法,并以工程实例验证了所提出方法的实用性。
Presuming impact of reinforced material as horizontally and uniformly distributed force on the bottom of embankment,it derives critical load and formula of critical load of foundation on reinforced material and central main stress with the formula of Flamant and Cerruti under polar coordination system and uniform strength theory. It proposes calculation method for critical filling height of horizontally reinforced embankment as well as verifies practicability based on engineering project.
