| 摘 要： | 目前的景观建筑设计中往往更注重建筑的景观性,而忽略了建筑的安全稳定性,导致景观建筑的整体抗震效果较差,在景观建筑设计中加入挡土墙设计可以有效提高其抗震性。为此,设计一种具有一定抗震性能的景观建筑挡土墙,利用建筑施工过程中保留的复合纤维材料、建筑垃圾以及纤维绳等作为土墙填充物,并加入具有一定抗拉能力的拉筋材料,以保持土墙内部的稳定性。考虑景观建筑通常注重外观视觉效果,使用"平改坡"设计,在墙体表面种植具有一定视觉冲击的植物,增加土墙自重,促进土墙整体结构的稳定性。分析挡土墙后面无限倾斜填土受力状态,选取菱形微小单元体作为研究对象,计算景观建筑的挡土墙土压力强度。实验证明,优化设计的景观建筑挡土墙结构可以有效增强景观建筑的整体抗震能力。

| Abstract: | At present, landscape architecture design often pays more attention to the view of the building while neglecting safety and stability. This leads to poor seismic response of the landscape building as a whole. Therefore, adding a retaining wall can effectively improve its earthquake resistance. For this reason, a type of retaining wall for landscape buildings with some seismic performance was designed in this paper. The composite fiber material, building refuse, and fiber rope retained in the construction process were used as the filling material of the earthen wall. To maintain the stability of the soil wall, tensile material of certain tensile strength was added to the earth fill. Because the landscape architecture usually pays attention to the visual effect of appearance, the design of "altering flat ground into slope" was used. Plants of a certain visual impact were installed on the wall surface to increase the self-weight of the earthen wall and to promote the stability of the overall structure of the soil wall. The stress state of infinite inclined backfill behind the retaining wall was then analyzed, and the rhombic micro-element was chosen as the research object to calculate the earth pressure strength of the retaining wall. The experimental results showed that the optimized design of the retaining wall structure can effectively enhance the overall seismic capacity of the landscape building. |
