【摘要】 为改善生土墙的抗震性能,采用纵向布置8#线、水平布置铁丝网等加强措施以及采用改性生土坯砌筑墙体,并采用MTS系统对墙体进行了低周往复加载试验.结果表明:试件在墙根部发生局部压坏,随着荷载的不断增加,裂缝逐渐展开并且不断向中间延伸,最终裂缝贯通生土墙破坏.墙体与底梁易发生粘结破坏,在施工中已予以重视.纵向设置8#线、水平设置铁丝网可以提高开裂荷载和极限荷载,且可以提高墙体的整体性,能显著改善墙体变形能力和耗能能力.更多还原

【Abstract】 In order to improve the seismic behavior of raw-soil wall,such reinforcing measures as arranging the 8#line in the vertical direction and wire mesh in the horizontal direction were adopted,and the modified adobe was utilized to build the wall. The low cyclic loading experiment on the wall was performed with the M TS system. The results show that the root of the wall is partially crushed,and the cracks gradually propagate and continuously extend to the middle with gradually increasing the load. Finally,the cracks penetrate the raw-soil wall,and the wall is destroyed. The cohesiveness failure between the wall and bottom beam occurs easily,and more attention should be paid in the construction. Through arranging the 8#line in the vertical direction and wire mesh in the horizontal direction,the cracking load,ultimate load and even the integrality of the wall can be enhanced. Furthermore,the deformation capacity and energy dissipation ability can be markedly improved.更多还原
