| 摘 要： | 通过离心模型试验揭示了土质路堑高边坡在开挖卸载过程中的变形特性及坡体应力变化特点,分析了土质路堑高边坡土体参数(密实度、含水量)变化对坡体变形特性和虚拟力(人为控制坡面变形而产生的力)的影响,以及两者之间的关系;讨论了在坡体的开挖卸载过程中,正在开挖卸载的坡面对上、下坡面的影响(通过坡面的变形及虚拟力的变化反映出来)规律.试验结果表明,坡体含水量的增加和密实度的减小均会改变坡体的应力状态,增大边坡侧向位移,降低边坡的稳定性.

| Abstract: | Through the centrifugal model tests,the paper reveals the deformation characteristics and stress of the soil cut high slope in the process of excavation and unloading and analyzes the influence of the changing soil parameters of the soil cut high slope(density and water content) on the deformation characteristics and fictitious forces(generated by the artificial control of the slope surface deformation),as well as the relation between them.It discusses the rule of the influence of the slope surface under ex... |
