摘要:
为了得到施工过程中填料和加筋材料的搭配、加筋材料设计的参数,依托德商高速的加筋土挡土墙,采用大型岩土软件PLAXIS,建立加筋土挡土墙内部稳定性分析模型。选择水平位移、竖向位移和安全系数作为评价指标,确定在合理范围内,挡土墙的稳定性随加筋长度的增加而增大,随着加筋材料竖向间距的减小而增加; 加筋长度越长,加筋材料竖向间距越小,对挡土墙水平位移的抑制作用越明显,对于竖向位移影响甚微。
Abstract:
In order to obtain the reasonable basis for the matching of filler and reinforced materials and the design parameters of reinforced materials in the construction process, the stability analysis model of reinforced retaining wall was established by PLAXIS, a program for geotechnical engineering, based on the reinforced retaining wall for Dezhou-Shangqiu expressway.The horizontal displacement, vertical displacement and safety factors were chosen as the evaluative indicators to determine that the stability of the retaining wall increases with the increase of the length of the reinforcement within a reasonable range and increases as the vertical spacing of the reinforced materials decreases; the longer the reinforcement length and the smaller the vertical spacing of the reinforced materials, the more obvious the inhibitory effect on the horizontal displacement of the retaining wall, and the vertical displacement is much less affected.
