摘要:

对四川地区常用的3种页岩空心砖分别进行不同受压面的抗压强度试验,取四、五、六孔3种孔洞形式的空心砖各90块,每种空心砖大面、条面和顶面抗压强度试验试件各为30块。计算了不同孔洞形式空心砖不同受压面的抗压强度变异系数,对比分析了不同空心砖同一受压面和同种空心砖不同受压面的强度离散性。比较正态分布和Weibull分布对页岩空心砖抗压强度分布特征的反映情况。通过Weibull分布对不同空心砖相同受压面及同种空心砖不同受压面的9组试验的抗压强度进行可靠度分析。结果表明:Weibull分布比正态分布更能反映空心砖抗压强度的分布特征规律; 空心砖的抗压强度离散性及其可靠度受孔洞形式影响,相同受压面的3种页岩空心砖中,四孔空心砖离散性较大,而六孔空心砖的抗压强度离散性最小,可靠度最好; 同种空心砖的不同受压面也影响空心砖的抗压强度离散性和可靠度,同种空心砖的3个受压面中,顶面抗压强度明显高于条面和大面的抗压强度,且顶面抗压强度分布更集中,离散性最小,可靠度最好。

Abstract:

The compressive strength tests of three kinds of shale hollow bricks widely used in Sichuan area were carried out on different compressive surfaces. 90 hollow bricks with four, five and six holes were selected, and the number of each kind of hollow brick in compressive strength tests of large, strip and top surfaces was 30. The variable coefficient of compressive strength of hollow bricks with different holes and different compressive surfaces was calculated, and the strength discreteness of different hollow bricks with the same compressive surface and the same hollow bricks with different compressive surfaces was compared and analyzed. The response of normal distribution and Weibull distribution to the compressive strength distribution characteristics of shale hollow bricks was compared. Through Weibull distribution, the reliability of 9 groups of tests on the same compressive surface of different hollow bricks and different compressive surfaces of the same kind of hollow bricks was analyzed. The results show that Weibull distribution can better reflect the distribution characteristics of compressive strength of hollow bricks than normal distribution; the discreteness and reliability of compressive strength of hollow bricks are influenced by the type of holes; the discreteness of four-hole hollow bricks in three kinds of shale hollow bricks with the same compressive surface is larger, while the discreteness of compressive strength of six-hole hollow bricks is the smallest. The different compressive surfaces of the same kind of hollow brick also affect the discreteness and reliability of the compressive strength of the hollow brick. Among the three compressive surfaces of the same kind of hollow brick, the compressive strength of the top surface is significantly higher than that of the strip surface and the large surface, and the distribution of the compressive strength of the top surface is more concentrated, the dispersion is the smallest and the reliability is the best.
