摘   要：在研发一种以玻璃轻石为骨料的轻质混凝土的基础上，研制了玻璃轻石混凝土自保温砌块。为了得到最优的自保温砌块的孔型设计方案，设计了三种自保温砌块孔型，利用ABAQUS有限元软件进行数值模拟，研究块型对热工性能的影响，得到有利用实际生产和工程应用的孔型方案。结果表明，三种块型的导热系数减小在17.1%以上。增大孔洞率、减小孔间距可以减小热桥的横截面积，有利于提高空心砌块的保温隔热能力。

Abstract: Based on the research and development of a kind of lightweight concrete with glass lightweight stone as aggregate, the self-insulation block of glass lightweight stone concrete is further developed. In order to obtain the optimal hole design of self-insulating block, three self-insulating block holes were designed. The ABAQUS finite element software was used for numerical simulation to study the influence of block type on thermal performance. Hole plan for production and engineering applications. The results show that the thermal conductivity of the three block types is reduced by 17.1% or more. Increasing the hole rate and reducing the hole spacing can reduce the cross-sectional area of the thermal bridge, which is beneficial to improve the thermal insulation capacity of the hollow block.
