| 摘 要： | 在提出非满布的H-V（水平－竖向）加筋的基础上，设计了非满布多层H-V加筋黏土的试验方案，以镀锌铁皮和有机玻璃为加筋材料进行了44组固结不排水三轴剪切试验。通过不同竖筋布置的加筋黏土三轴试验研究了加筋黏性土的应力-应变关系、强度特性及破坏形态，探讨了不同加筋高度、不同围压及不同筋材对加筋黏土强度的影响。试验结果表明：相对于无筋土及传统的水平加筋土而言，其峰值偏应力和抗剪强度均有大幅度提高。

| Abstract: | Based on non-full horizontal-vertical (H-V) reinforced clay, a series of consolidated undrained triaxial tests are carried out to investigate the strength and deformation properties of clay reinforced with H-V inclusions, in which the galvanized iron sheet and plexiglass are used as reinforcing materials. The behaviour of clay reinforced with different vertical reinforcements is studied in terms of stress-strain relationship, strength property and failure mode. The influences of vertical reinforcement, confining pressure and reinforcing materials on the strength of reinforced clay are discussed. The results show that the peak deviator stress and shear strength increase greatly for clay reinforced H-V reinforcing elements as compared to unreinforced clay and clay reinforced with conventional horizontal inclusions. |
