摘要
针对闽清县X127线省璜镇省璜至谷洋段公路改建工程某处边坡,对其进行开挖的稳定性分析。通过FLAC3D软件,进行“层-面-层”模型的构建并对其进行分析,同时设定3个监测桩对特征点的位移以及水平应力进行分析,以得到滑面,进行开挖稳定性的模拟。依据推力以及稳定参数,进行相应的锚固设计,同时经过验证,方案实际可行,能够保证开挖边坡坡体稳定。
The stability analysis of excavation was carried out on a slope of the reconstruction project of Huangzhen to Guyang section of X127 Line X127 in Minqing County.Through FLAC3D software,the"layer-surface-layer"model is constructed and analyzed,and three monitoring piles are set to analyze the displacement and horizontal stress of the feature points to obtain the slip surface and simulate the excavation stability.According to the thrust and stability parameters,the corresponding anchorage design is carried out,and the scheme is verified to be feasible to ensure the stability of the excavated slope.
