摘要
从试样三轴剪切受力条件出发,分析了损伤土、素土和加筋土的极限应力莫尔圆的几何关系,得到了三者在强度联系上的数学表达式,讨论了加筋材料对损伤土强度的补偿效果.进行了损伤土、素土和加筋土的三轴试验,验证了以上解释的合理性,从而清晰地理解加筋土作用的机理.
Through analysing the Mohr circles of damaged soil,pure soil and reinforced soil,these formulas for describing the relation among the strengths of the three kinds of soils are obtained;and then the contribution of reinforcement to the strength of damaged soils is discussed.In order to prove the reasonableness of formulas,the triaxial shear tests on the three soils are carried out.The results from the triaxial shear tests show that the formulas are reasonable,so as to help people to understand the mechanism of interaction between reinforcements and soils easily.
