为促进竹格栅在山区土石混合路基中的应用，研究了竹格栅的力学性能，对比分析了不同竖向荷载作用下竹格栅对土石混合料的加固效果和界面特性。结果表明，竹材增强体的拉伸强度(伸长率为2%)为50.21kN/m，平均拉伸强度为236.01 Mpa。此外，竹材增强材料还具有良好的剪切和弯曲性能。总体来说，双向竹网对土石混合路基的加固效果要好于单轴竹网。在采用单轴竹网架的情况下，其拔出曲线一般为应变软化型。对于双向竹制网架，由于咬合力的存在，其拔出曲线通常呈应变硬化型。与单轴竹栅相比，双向竹栅加筋土界面处的摩擦系数较大，界面剪应力提高了72.2~91.2%。
To promote the application of the bamboo grid in the soil–rock mixture subgrade in mountain areas, the mechanical properties of bamboo reinforcement were investigated in this study, and the reinforcement effect and interface characteristics of uniaxial/biaxial bamboo grid on the soil–rock mixture under different vertical loads was comparatively analyzed. The results show that the tensile force (2% elongation) of the bamboo reinforcement is 50.21 kN/m, and its average tensile strength is 236.01 MPa. Moreover, bamboo reinforcement has excellent shear and flexural properties. In general, the reinforcement effect of the biaxial bamboo grid on the soil–rock mixed subgrade is better than that of the uniaxial bamboo grid. In the case of using a uniaxial bamboo grid, its pull-out curve is generally a strain-softening type. As for the biaxial bamboo grid, due to the existence of bite force, its pull-out curve usually presents a strain-hardening type. Compared with the uniaxial bamboo grid, the friction coefficient of the reinforcement–soil interface using the biaxial bamboo grid is higher, and the interfacial shear stress is increased by 72.2–91.2%.
