摘要
黏聚力对土钉墙的变形、稳定性和经济性影响显著。利用FLAC3D数值分析软件,模拟了黏性土在不同黏聚力时对土钉墙的位移、安全系数及潜在滑动面贯通程度的影响。分析结果表明,随着土体黏聚力的逐渐提高,土钉墙的位移明显减小,安全系数显著增大,坡体内滑动面的贯通程度明显降低,潜在滑移区的范围不断缩减,土钉墙整体稳定性明显增加。
The cohesion has a significant influence on the deformation,stability and economy of the soil nailing wall.Using FLAC3D numerical analysis software,the effects of the cohesive on the displacement and safety factor of the soil nailing wall and the penetration degree of the potential sliding surface were simulated.The results show,as the soil cohesion gradually increases,the displacement of the soil nail wall is obviously reduced,the safety factor is significantly increased,the penetration degree of the sliding surface in the slope is obviously reduced,the range of the potential slip zone is continuously reduced,and the overall stability of the soil nailing wall is obviously increased.
