摘    要:应用Mohr-Coulomb屈服准则,推导了注浆后岩土体的屈服函数.根据位于205国道上某土质边坡的实际情况,利用现场实测数据和实验数据,分别对注浆前后坡体的破坏状态、不同位置位移的变化情况以及坡体的整体稳定性等方面进行了模拟计算.结果表明,注浆后岩土体的弹性区域显著增大,侧向位移明显减小,而岩土体的剪应力屈服区域则由集中趋于分散.

关 键 词:岩土体  中高压注浆  性能分析  数值模拟  内聚力  内摩擦角  土体注浆  性能分析  Properties  Masses  Soil  Rock  Analysis  屈服区域  剪应力  侧向位移  弹性区域  结果  模拟计算  整体稳定性  变化  位置  破坏状态  坡体  实验数据  实测数据

Abstract:Based on the Mohr-Coulomb failure criteria, the yield functions were deduced under the passive earth pressure condition. By using of the in-situ test data and assisted by FLAC2D, the numerical analysis of an un- stable soil slope located at the No.205 national highway is carried out. The results show that the increment of elastic area and the decrement of lateral displacement in the soil slope after cement-grouting are notable, also the strain- sheared area and the volume strain area tend to dissipation.
Keywords:rock and soil mass  middle-high pressure grouting  property analysis  numerical simulation  cohesion  friction angle
