Wudu is the area where using typical rammed earth rural houses in Gansu province.In experiments two wall specimens are built using local material and local construction technology,and the shearing strength of wall is investegated by pseudo-static test,the results show（1） the overlying load on the wall has greater effect on horizontal load capacity and deformation of the wall,with the overlying load from 10 kN to 18 kN,cracking load and ultimate load increased by 217% and 359%,ultimate top displacement is reduced by 30%;（2） the rammed earth wall is always destroyed along the horizontal and vertical contacts between layers,and eventually is fragmented into blocks with the role of horizontal cyclic loading.At last,this paper recommend to reinforce the rammed earth bearing wall of the existing rural houses with iron mesh.
