从理论和试验研究两方面入手,结合实际工程,进行分级加载试验,分析与普通混凝土强度等级相同的轻骨料混凝土空心板的挠度和变形.结果表明,在设计荷载范围内,轻骨料空心板相对残余变形较小,荷裁-挠度关系近似于线性关系,弹性较好.但是,轻骨料混凝土空心板开裂荷载较小,裂缝出现较早,发展较快.试验分析为轻骨料混凝土在桥梁中的应用提供了宝贵的参考价值.

Based on the theory and experiment,together with practical project,performance and destructive features of light-weight aggregate concrete hollow board were analyzed through many grading loading tests,and the distortion of the board was defined compared and studied between normal concrete and light-weight aggregate concrete hollow board under the same intension.As the result shows,within the scope of designed load,light-weight aggregate concrete hollow board has a relatively small remnant distortion,and an approximately linear relationship between load and flexibility exists,and the board is in a flexible performing state.But light-weight aggregate concrete hollow board has a small cracking load,and its crack appears early and splits quickly.The test analysis will be helpful for the application of light-weight aggregate concrete in the building of bridges.
