摘要:
通过对含有锚杆的水泥砂浆试件进行单轴压缩试验,系统地研究了锚杆的布置方式对试件强度和变形特性的影响。研究结果表明:(1) 当锚杆横截面的连线呈直线或者正方形时,随着锚杆数量的增加,试件的抗压强度、弹性模量均会逐渐增加,试件峰值应变的变化没有固定规律;(2) 当锚杆横截面的连线呈直线时且试件中的锚杆数量相同时,荷载方向垂直于锚杆横截面的连线时试件的抗压强度和弹性模量,大于荷载方向平行于锚杆横截面的连线时试件的抗压强度和弹性模量。
Abstract:
In order to examine the effect of the arrangement of the bolt on the strength and deformation of the cement mortar specimen, uniaxial compressive tests on the cement mortar specimen with bolt were carried out. The test results show that (1) the connection of the cross section of the bolt is linear or square, with the increasing number of bolts, the compressive strength and elastic modulus of the specimen will gradually increase, and the change law of peak strain is not fixed. (2) When the connection of the cross section of the bolt is linear and the number of bolts in the specimen is the same, both the compressive strength and elastic modulus of the specimen, when the loading direction is perpendicular to the connection line of cross section of bolts, are higher than those when the loading direction is parallel to the connection line of cross section of bolts.
