摘　　要：近年来草皮护坡越来越多地出现在实际工程当中,但是相关研究却是一个相对较新的领域。传统的边坡工程加固措施,大多采用砌石挡墙及喷混泥土等护坡结构,仅仅起到了一个保护水土流失的作用。现基于土力学,弹性力学和生态学原理和方法,采用室内直剪试验的技术路线来探讨5种不同固土植物的根系对土体抗剪强度的影响,以及根和土复合体的抗剪特性。不断的研究和应用实践完善草皮护坡的科学基础,使其实用性与科学性进一步融合,并扩大和加深其工程应用的理论内涵和应用范围。In recent years,Turf revetment engineering more and more appear in the practical project,but the research is a relatively new field. The traditional slope engineering reinforcement measures,most of the stone retaining wall and mixed spraying structure soil slope,only played a role in the protection of the soil and water loss.Based on soil mechanics,elastic mechanics and the ecological principles and methods,technical route using indoor direct shear test to explore the effects of 5 different soil plant roots on shear strength of soil,and the shear characteristics of root and soil complex. Research and applicaton of practice constantly improve the scientific basis of turf,making it practical and scientific further fusion,and expand and deepen the theoretical meaning and scope of its engineering applications.
