Pile-supported damping reinforced soil abutment and construction method thereof
The invention discloses a pile-supported damping reinforced soil abutment which comprises a road and bridge connecting and supporting system and a reinforced soil abutment system; the reinforced soilabutment system comprises a reinforced soil complex formed by inserting a rib material into filled soil, a modular wall surface and a supporting structure, and the road and bridge connecting and supporting system is arranged at the top of the reinforced soil complex; the modular wall surface is positioned on the outer side of the reinforced soil complex; the supporting structure is vertically mounted in the reinforced soil complex, and the lower end of the supporting structure penetrates through the reinforced soil complex and then is anchored in a foundation. The supporting structure comprises a supporting pile, a buffer layer wrapping the periphery of the pile and an energy absorption material layer arranged on the top of the pile. The energy absorption material layer is in contact withthe bottom of the road and bridge connecting and supporting system. The pile-supported damping reinforced soil abutment has the beneficial effects that the energy absorption material layer is arrangedat the top of the supporting pile, vertical impact force can be effectively buffered, the pile top is prevented from being damaged, the buffer layer is arranged on the periphery of the pile, concentrated loads can be prevented from being directly applied to the pile body, shear damage is avoided, and the stability of the bridge abutment is further improved.
本发明公开了一种桩承式减震加筋土桥台，包括路桥连接支承系统和加筋土桥台系统，所述加筋土桥台系统包括由筋材插入填土形成的加筋土复合体、模块式墙面及支承结构，所述路桥连接支承系统设于加筋土复合体的顶部；所述模块式墙面位于加筋土复合体的外侧；所述支承结构竖向安装于加筋土复合体内，支承结构下端穿过加筋土复合体后锚固于地基中；所述支承结构包括支承桩、包覆于桩周缓冲层，以及设于桩顶吸能材料层；所述吸能材料层与路桥连接支承系统底部接触。本发明的有益效果为：在支承桩的顶部设置吸能材料层，可以有效缓冲竖向冲击力，防止桩顶受到破坏，在桩周设置缓冲层，可以防止集中荷载直接施加在桩身上，避免发生剪切破坏，进一步增加了桥台的稳定性。
