摘要
基于库区边坡工程,利用PLAXIS3D有限元软件进行分析,对比不同含水率时边坡的变形差异,并对抗滑桩支护效果进行综合评价,得到结论:随着含水率增大,边坡变形显著增大、滑移范围扩大,同时边坡安全系数急剧下降;暴雨工况下,边坡处于不稳定状态;抗滑桩支护结构能显著控制边坡的变形,暴雨工况下,库岸边坡稳定性安全系数为1.32,边坡整体处于稳定状态;抗滑桩支护结构能显著提升该库岸边坡的整体稳定性。
Based on the slope engineering of a reservoir area,this paper uses PLAXIS3D finite element software to analyze,compares the deformation differences of the slope with different water content,and makes a comprehensive evaluation of the anti slide pile support effect.The conclusions are as follows:with the increase of water content,the slope deformation increases significantly,the sliding range expands,and the safety factor of slope decreases sharply.Under the rainstorm condition,the slope is unstable.Although the anti slide pile support structure can significantly control the deformation of the slope,under the rainstorm condition,the stability safety factor of the reservoir bank slope is 1.32,and the whole slope is in a stable state.Although the anti slide pile supporting structure can significantly improve the overall stability of the reservoir bank slope.
