摘要

大型三轴固结排水剪切试验表明：土工带加筋后土体的破坏强度和破坏应变均得到提高。从加筋土和未加筋土的强度包线看出，加筋前后土体的强度曲线基本平行，摩擦角相等，粘聚力提高。通过分析加筋土的应力-应变关系试验曲线，研究土工带加筋素碎石土的抗剪强度特性，提出土工带加筋土的抗剪强度表达式。为进一步研究土工带素碎石土加筋机理提供试验基础。

Abstract

The large-scale triaxial consolidation drained shear tests have been carried out for geobelt reinforced crushed gravel soil and non-reinforced crushed gravel soil. The effects of reinforcement on stress-strain and shear strength of gravel soil are studied. The experimental results show that the failure strength and strain of the reinforced soil are increased. It is seen that the curves of strength between reinforced and non-reinforced soil are almost completely parallel; and their friction angles are fairly same; cohesion of reinforced soil is higher than the non-reinforced soil by the strength envelopes of reinforced and non-reinforced soil. The properties of shear strength of geobelt reinforced crushed gravel soil are studied by analyzing the relationship of stress-strain of reinforced crushed gravel soil. A calculation formula of shear strength of geobelt reinforced crushed gravel soil is drawn. This paper provides an experiment basis for studying mechanism of geobelt reinforced crushed gravel soil further.
