摘要
以彭湖高速公路K26+150高填路堤为研究对象,通过对现场调研并采样开展室内土的物理性质试验、击实实验和直剪试验。在不同压实度情况下取得粘聚力c、内摩擦角φ值的基础上,采用极限平衡法分析不同粘聚力c、内摩擦角φ、容重γ、坡高H和坡比m情况下高路堤的稳定性,并探讨了各种强度参数与边坡稳定性的敏感性关系。初步表明内摩擦角φ和坡比m对路堤边坡稳定性影响更为敏感。
The physical nature of the indoor soil, compact test and direct shear test are carried out by means of on-the- spot investigation adopting high embankment along Penghu highway as the researching object. Based on c, φ values achieved in different degree of compaction, limit equilibrium method is used to analyze stability of high embankment under different cohesion c, friction angle φ, bulk density γ, slope height H and the slope ratio m. The sensitive relationship between various strength parameters and slope stability is also discussed. The preliminary result shows that effect of the internal friction angle φ on the slope stability is more sensitive than slope ratio m.
