玛尔挡改线公路高边坡稳定性分析及生态治理

通过对玛尔挡改线公路高边坡工程地质及水文地质条件调绘探查、岩层节理裂隙统计，采用赤平极射投影法对边坡进行稳定性分析。分析结果显示，高边坡整体处于稳定状态，但如果不采取防护措施，边坡岩土层经过长期的风化剥蚀，边坡局部会逐渐趋于欠稳定状态。根据该地区气候、环境及以往经验，提出采用锚拉式混凝土挡墙结合柔性防护网的生态防护措施对边坡进行防护，实施效果良好。 

Stability analysis and ecological management of the Maerdang highway slope

Based on the survey of engineering geology and hydrogeological conditions, statistics of joints and fissures of Maerdang highway slope, the stability analysis of rock slope stability is carried out by the method of hemispherical projection method. The results show that the whole slope is stable. But if no protective measures are taken, after a long period of weathering and erosion of rock and soil, the slope will gradually be in less stable state. According to the climatic environment and the past experiences, this paper puts forward the ecological protective measures of slope protection with anchor pull type concrete retaining wall combined with flexible protective net, and the implementation effect is good.
