摘要
地仗层的材料性能影响着造像和壁画的变形破坏。为了探究纤维材料对地仗层的修补效果,文中采用传统麻刀纤维与现代碳纤维对粉质黏土仗层进行了改性试验。结果表明碳纤维和麻纤维的掺入均能显著提升土体强度,其中碳纤维改善强度的效果更好;纤维的掺入能有效抵抗土体干缩形变,0.75%的麻纤维掺入量效果更优。
The material properties of fresco plasters affect the deformation damage of the statues and murals.To in⁃vestigate the influence of traditional fiber materials on the reinforcement characteristics of the plasters,this paper us⁃es traditional fibrilia and modern carbon fiber to modify the plasters of powdery clayey soil.The results show that the incorporation of both carbon fiber and fibrilia can significantly improve the strength of the soil,among which carbon fiber is more effective in improving the strength;the incorporation of fiber can effectively resist the dry shrinkage de⁃formation of the soil,and the control effect of 0.75%fibrilia incorporation is better.
