摘   要：研究了高强硅酸盐墙板的抗压性能及破坏形态，提出了标准试块受压应力-应变本构方程，通过ABAQUS有限元软件进行了数值模拟，并与试验结果进行了对比。结果表明：标准试块受压应力-应变全过程曲线的形状和普通混凝土相似，峰值应力前曲线接近直线，达到峰值应力后，应力迅速跌落；可采用二段式曲线拟合高强硅酸盐墙板标准试块的单轴受压应力-应变关系，得出其本构模型；试件的破坏形态为脆性破坏，延性较差，抗压试件破坏时两板面出现竖向裂缝，两孔间肋出现竖向裂缝和斜裂缝；试件承载力较高，满足现有规范对建筑用隔墙条板的强度要求。

Abstract: The compressive properties and failure mode of high-strength silicate wallboards were studied, and the stress-strain constitutive equation of the standard test block was put forward. The numerical simulation was carried out by ABAQUS finite element software, and the results were compared with the experimental results. The result shows that the shape of the compressive stress-strain entire process curve of the standard test block is similar to that of ordinary concrete, and it increases approximately linearly before reaching the peak stress, and drops rapidly after reaching the peak stress. The two-section curve can be used to fit the uniaxial compressive stress-strain relationship of the standard test block of the wallboard, and its constitutive model is given. The failure mode of the specimen is brittle failure with poor ductility, and when the compressive specimen is damaged, vertical cracks appear on the two plates, and vertical cracks and oblique cracks appear on the ribs between the two hole ribs. The bearing capacity of the specimen is high, which can meet the strength requirements of the existing codes for artition board used in buildings.
