中文摘要：
软岩边坡失稳破坏与卸荷应力引起的坡体变形、蠕变与降雨有关，正确确定其对坡体变形的影响是合理设置加固支挡结构的关键。通过地质力学模型试验，研究软岩高边坡在开挖及降雨时坡体的稳定性及变形变化规律，分析支挡结构对边坡变形的影响机理。试验结果表明，在开挖过程中及时地施加支挡结构，可以减小施工期间坡体的变形；同时，支挡结构可以有效地抑制坡体的蠕变变形，特别对坡体中下部的蠕变变形抑制效果更显著。
英文摘要：
The excavation, the creep of soft rock and rainfall are the main reasons for the failure of the soft rock slope. The deformation and stability of soft rock slope under excavation and rainfall, as well as the effect of the supporting system on slope deformation are analyzed by physical modeling. It is suggested that the immediate supports are necessary to decrease the deformation of slope under excavation. Meanwhile, the supporting system can effectively restrict the creep deformation of soft rock slope, especially for the areas of the middle and bottom of the slope.
