摘　　要：夯土墙广泛分布于我国偏远乡村等一些经济不发达地区,制造工艺简单,采用的材料强度低,整体性差,自身力学性能比较差,抗震性能较低。现有夯土墙加固方式还存在一些不足。文中采用一种新型的高延性混凝土加固夯土墙,用ABAQUS软件对加固后墙体的力学性能和抗震性能进行数值模拟,并和现有的加固夯土墙材料进行对比分析,结果发现,经过高延性混凝土加固的墙体在力学性能和抗震性能方面,均优于纤维复合土加固的夯土墙。Rammed earth walls are widely distributed in some economically underdeveloped areas such as remote villages in China,their manufacturing technology is simple,the materials used have low strength and poor integrity,so its mechanical properties arer elatively poor,and the seismic performance is relatively low.There are stills ome deficiencies in the existing way of rammed earth wall reinforcement.In this paper,we use a new type of high tensile concrete to cement rammed earth wall,simulate the mechanical and seismic properties of the reinforced wall with ABAQUS software,and compare it with the xeisting reinforced rammed earth wall materials.Combined with hte results,it is found that the wall reinforced with high ductility concreteis better than the rammed earth wall reinforced with fiber composite soil both in terms of mechanical properties and seismic properties.
