The invention provides an assembly type retaining wall damping and energy-dissipating structure which is composed of an assembly fixing plate (1), a damping and energy-dissipating unit (2), a pressurizing fastener (3) and a composite geotechnical drainage network (4). The assembly fixing plate (1) and the pressurizing fastener (3) are used for pressurizing the damping and energy-dissipating unit (2), so that the internal stress of the damping and energy-dissipating unit is the same as the active soil pressure at the position, the composite geotechnical drainage network (4) does not generate too large deformation under the action of the soil pressure behind a wall, and the working efficiency of the composite geotechnical drainage network (4) is guaranteed. When the assembly type retaining wall damping and energy-dissipating structure is in an earthquake state, the damping and energy-dissipating unit (2) consumes earthquake wave energy by generating elastic deformation, energy directly acting on the retaining wall is reduced, and therefore the soil moving pressure acting on the retaining wall is reduced, and finally the power stability of the retaining wall is improved. Compared with the prior art, the assembly type retaining wall damping and energy-dissipating structure has the beneficial effects of being simple in structure installation, convenient to operate and the like, and the power stability of the retaining wall is improved on the premise that the good drainage condition behind the retaining wall is guaranteed.
一种由装配固定板(1)、减震吸能单元(2)、加压紧固件(3)、复合土工排水网(4)构成的装配式挡土墙减震吸能结构。使用装配固定板(1)和加压紧固件(3)对减震吸能单元(2)进行加压，使减震吸能单元内部应力与该处主动土压力相同，以保证复合土工排水网(4)在墙后土压力作用下不产生过大变形，确保其工作效能。处于地震状态时，减震吸能单元(2)通过产生弹性形变消耗地震波能量，减少直接作用在挡土墙的能量，从而减少作用与挡土墙的动土压力，最终提高了挡土墙的动力稳定性。与现有技术相比，本发明具有结构安装简单，便于操作等优势，并在保证挡土墙后良好排水条件的前提下，提高了挡土墙的动力稳定性。
