以彭(泽)-湖(口)高速公路K26+150路基填土为研究对象,采用DIK-3403非饱和土水特征仪测得非饱和土含水率与基质吸力的关系,再根据获得的曲线结合经验公式估算几种含水率下的非饱和土的强度,开展路基边坡的极限平衡分析,对比不同含水率以及饱和土条件下彭湖高速公路K26+150路基边坡的稳定性,验证非饱和理论在路基边坡稳定中的适用性。
Based on the K26 + 150 embankment filling of Peng (Ze) -hu (expressway) expressway, the relationship between the moisture content of unsaturated soil and the matrix suction measured by DIK-3403 unsaturated soil-water characteristics was obtained. According to the obtained curve Based on the empirical formula, the strength of unsaturated soils under several moisture contents was estimated and the limit equilibrium analysis of subgrade slope was carried out. The stability of Slope of K26 + 150 subgrade at Penghu Expressway under different water content and saturated soil condition was compared. Suitability of Saturation Theory in Stability of Subgrade Slope.
