钻芯法检测砌体抗剪强度影响因素分析及测强曲线建立

通过试验数据对比,分析砌块种类、砂浆种类、砌体厚度等因素对钻芯法检测砌体抗剪强度及砌筑砂浆立方体抗压强度的影响,将不同砌块材料分类为烧结普通砖、烧结多孔砖、混凝土实心砖、混凝土多孔砖、蒸压粉煤灰砖,各类砌块材料砌筑的砌体应分别建立测强曲线,同时介绍山东省钻芯法检测砌体抗剪强度和砌筑砂浆立方体抗压强度测强曲线。

Analysis of Influence Factors of Detecting Shear Strength of Masonry by Drilled Core Method and Establish the Detecting Strength Curve

By compare with experimental data, this paper analyze the influence of the block type, mortar type, thickness of the masonry and other factors to deteet shear strength of masonry and cubic compressive strength of mortar by drilled core method. Different block materials classified as fired Ordinary brick, fired perforated brick, solid concrete brick, perforated concrete brick, autoclaved fly ash brick. All kinds of block materials should be established respectively measured curves, at the same time introduce detecting strength curve of detect shear strength of masonry and cube compressive strength of mortar by drilled core method in Shandong province.
