摘　　要：为研究湛江黏土的各向异性特征,开展了不同取样角度的固结试验、直剪试验和无侧限抗压强度试验,分析了其固结变形、强度和破坏形式的各向异性。试验结果表明,湛江黏土在不同取样角度下的结构强度、抗剪强度及破坏形式呈各向异性特征,其结果对解决结构性黏土工程的设计计算及安全稳定具有一定参考意义。A series of consolidation test,direct shear test,unconfined compression test are conducted to explore the anistropic properties of Zhanjiang clay under different angles.The results show that:significant anisotropy is observed on the structural strength,shear strength and failure mode of Zhanjiang clay under different angles.It is of a great reference significance to solve the design calculation and safety and stability of structural clay engineering.
