摘要:
针对我国村镇大量在役生土结构民居抗震性能低的问题,提出单面钢丝网水泥砂浆加固夯土墙体的方法,研究用该法
加固的生土墙体的受力性能及抗震性能.设计了5 片夯土墙试件进行拟静力试验,在恒定竖向荷载下,对试件施加低周反复
水平荷载,研究墙体在地震水平荷载作用下的破坏过程和破坏形态,分析夯土墙体的滞回曲线和骨架曲线特征,得到加固后
和未加固夯土墙体的极限荷载和极限位移,验证了采用钢丝网水泥砂浆面层加固夯土墙体的效果,分析了加固后墙体在地震
水平荷载作用下的破坏机理.研究表明:采用钢丝网水泥砂浆面层加固可明显提高夯土墙体的承载能力和变形能力,可有效
避免夯土墙体在地震作用下的倒塌破坏.
Abstract:
This paper proposed an easy construction method that strengthening rammed-earth wall with single side Ferro-cement
surface layer and studied the reinforced the mechanical behavior and seismic behavior of the reinforced raw soil walls by this method.
Five rammed-earth wall specimens were designed. Vertical loading and low cycle reversed horizontal loading are carried out on
specimen aimed to study the failure process, failure mode, failure mechanism and hysteretic curve and skeleton curve feature. The
ultimate load and ultimate displacement of the reinforced rammed-earth wall and unreinforced rammed-earth wall are also obtained.
The reinforcement effect is also verified. The results show that reinforcement method proposed in this paper have remarkable results
on the load-carrying and deformation capacity of the rammed-earth wall, and effectively avoided the rammed-earth wall’s damages
and collapse.
