摘要
通过碎石土和加筋碎石土的大型三轴试验,分析了土工带加筋碎石土的变形特性和土工带加筋对碎石土应力-应变关系的影响,采用双曲线函数拟合加筋土体的应力-应变试验曲线,建立了土工带加筋碎石土的非线性模型以克服经典的刚塑体模型不能反映加筋土体在达到破坏荷载前的变形形态的缺点,提出了土工带加筋土体切线模量的计算公式,该模型能正确反映土工带加筋土体的变形特性,在岩土工程方面有一定的实际应用价值。
The large-scale triaxial tests have been carried out for crushed gravel reinforced by geobelt and non-reinforced. crushed gravel. The influence of geobelt reinforcement on stress-strain relation of crushed gravel is analyzed. The stress-strain curves of geobelt reinforced crushed gravel may be matched by a hyperbola function. A calculation formula of tangent modulus of geobelt reinforced crushed gravel is provided.
