摘要:
为了探讨高填方加筋土桩板式挡墙结构的破坏模式,探究高填方边坡稳定性的各类影响因素,结合实际工程,利用PLAXIS有限元软件建立数值模型,计算得到了边坡潜在破裂面位置、稳定安全系数、结构内力及位移。结果表明:滑裂面位置出现在加筋土体的边缘;边坡安全系数随筋带强度的提高而增大,随筋带长度的提高亦增大,但当筋带长度过大时,对提高安全系数作用不大;边坡安全系数随抗滑桩长度增大而增大,但长度过大时,对安全系数提高作用很小,因此应合理设计桩长;土体性质对边坡稳定安全系数影响显著,因此工程中要优先选用性质较好的填土。
Abstract:
To discuss the failure mode of high fill slope supported with reinforced earthretaining wall and pile slab wall and to explore the various affecting factors of the stability of the high embankment slope, we established a numerical model by using PLAXIS finite element software in light of the actual engineering and obtained the position of the potential fracture surface, the stability safety factor, the internal force, and the displacement of the structure. The results show that the slope safety factor increased with the increase of the reinforcement strength and length, while the overlength of the reinforcement has little effect on improving the safety factor. The safety factor of slope increases with the increasing length of antislide pile, however, the overlength of antislide pile plays a little role in improving the safety factor. Therefore, the antislide pile should be rationally designed. The soil property has significant influence on the safety factor of slope stability, so it is necessary to choose the fillings with good property in the project.
