摘　　要：根据基坑开挖导致的土体应力特点及基坑开挖中土体的排水条件,对施工现场的原状广州软土,按与土体沉积面的不同倾角取土样进行常规三轴固结不排水剪切试验,对其各向异性性状进行了研究探讨,结果表明其各向异性导致的抗剪强度差异明显,对基坑工程设计计算及确保基坑安全稳定有一定的指导意义。Following the earth stress characteristic and drainage condition in foundation excavation,selecting original soft clay according to earth aggradations face and different obliquity in construction spot of Guangzhou,and doing consolidated undrained triaxial compression test, we had studied the Guangzhou soft clay of its anisotropism. The test shows that Guangzhou soft clay is distinctness in shear strength. The distinctness is cause by anisotropism, The test result has great help to foundation project designed and foundation pit safety and its stabilization.
