摘要/Abstract

摘要： 经分析,冻融是造成隆盛庄古建筑墙体产生病害的主要原因。为了进一步研究严寒环境对古建筑墙体损伤劣化的影响,通过对青砖试样进行冻融试验,分析冻融前后质量、抗压强度和表面硬度的变化规律;基于Weibull分布,分别建立了质量、抗压强度和硬度3个指标下的冻融损伤模型,并通过统一3个损伤模型的形状参数(m)值对模型进行了修正。结果表明:青砖材料的抗压强度、质量损失量和表面维氏硬度随冻融次数的增加呈指数型下降;相同冻融循环次数下,表面硬度的损伤程度远比质量和抗压强度的损伤程度大;建立的Weibull损伤模型与试验曲线具有较高的吻合度,修正后的冻融损伤模型可以较好地反映青砖在严寒环境下的损伤规律。

Abstract: Analysis suggested that freeze-thaw is the main reason of causing severe diseases in the blue brick wall of Longshengzhuang ancient buildings. In order to study the effect of severe cold environment on the deterioration ancient building walls, the freeze-thaw test of blue brick specimen was conducted, and the changes of weight, compressive strength and surface hardness before and after freeze-thaw were analyzed. The Weibull distribution theory was used to establish the damage model of the blue brick in freeze-thaw environment under the three indexes of weight, compressive strength and hardness, and the model were modified by unifying the format factor m value of the three damage models. The results show that the compressive strength, mass loss amount, and surface Vickers hardness show an exponential decline with the increase of freeze-thaw cycles; the damage degree of surface hardness is higher than weight and compressive strength under the same freeze-thaw cycles. The Weibull damage model of blue brick under freeze-thaw cycle has a high degree of consistency with the experimental curves. The modified freeze-thaw damage model also reflects the damage law of blue brick in severe cold environment.

Key words: blue brick of ancient building, freeze-thaw cycle, weight loss, compressive strength, hardness, damage model
