摘要
传统的黄土路基高边坡易受地表水的影响而产生剥落、崩塌、不均匀沉降等病害,且其防护手段主要采用圬工结构,其严重影响路侧美观。为此,依托山西某高速公路的工程实例,利用数值模拟手段分析黄土路基高边坡的塑性区及竖向位移分布情况,评价其整体稳定性;并有针对性地制定了土工格室生态防护方案,利用现场观察手段对防护效果进行全面评价。研究成果对类似工程具有较强的参考价值。
Relying on the engineering example of a highway in Shanxi Province, this paper analyzed the plastic zone and vertical displacement distribution of loess subgrade high slope by using the numerical simulation means, and evaluated its overall stability. It also formulated the ecological protection scheme of geocell in a targeted manner, comprehensively evaluated the protective effect by using the field observation. The research results had strong reference value for the similar engineering.
