摘要

为了研究古尔班通古特沙漠砂掺量对沙漠砂混凝土轴心受压性能的影响,试验设计了11组沙漠砂混凝土棱柱体,通过轴心加载试验观察其破坏过程和破坏形态,并获取其峰值应力、峰值应变、弹性模量和荷载-位移全过程曲线。最后,通过拟合分析,提出了沙漠砂混凝土的本构方程。试验结果表明:沙漠砂混凝土棱柱体的各项力学性能均比普通混凝土有所降低,但其破坏过程、破坏形态、应力-应变曲线等性能都与普通混凝土十分相似。
        11 groups of sand concrete prism were designed for the experiment to study the influence of the Gurbantonggut desert sand content on the compressive properties of desert sand concrete(DSC).Then,the damage process and failure mode of DSC were obtained by the axial loading test,meanwhile,the peak stress,peak strain,elastic modulus and load-displacement curves were also obtained by analysis.The stress-strain curves calculation formula of DSC was proposed by fitting analysis.Test results shown that the mechanical properties of DSC prism were lower than that of ordinary concrete,while the damage process,failure mode and load-displacement curves of DSC were very similar to ordinary concrete.
