摘要
在常规剪切仪上进行了砂土及加筋砂土的三轴排水试验,确定了Duncan-Zhang非线性模型计算参数,探讨了加筋砂土的强度特性及作用机理。试验结果表明:加筋土应力-应变具有非线性关系;加筋土抗剪强度指标随加筋层数的增大而增大;土工织物在小应变时所起的作用较小,大应变时作用明显。
It conducts triaxial drainage tests of sand and reinforced sand on the routine shear instrument,decides computational parameters of Duncan-Zhang nonlinear model and approaches the characteristic of intensity and mechanism of function of reinforced sand.The outcomes show that the stress-strain of reinforced sand has nonlinear relations;the shearing resistance index of reinforced sand increases along with the increase of reinforced layer and;the function of geotextile is smaller as the strain is small and remarkable function as the strain is great.
