摘　　要：对12个不同砂浆砌筑的不同高厚比的机制生土砖砌体进行轴心抗压试验,获得机制生土砖砌体的应力-应变关系曲线。通过分析应力-应变关系曲线,得到机制生土砖砌体的变形模量和泊松比的试验值。探讨了机制生土砖砌体变形模量和泊松比的取值方法,分析了砂浆中不同掺料对机制生土砖砌体变形模量和泊松比的影响,可为生土材料制定统一标准提供参考。The axial compressive tests of 12 raw-soil mechanism brick masonry specimens with different depth-thickness ratios and mortars were carried out,and the stress-strain curve of raw-soil mechanism brick masonry was obtained. Through the analysis of the stress-strain curve,the test values of deformation modulus and poisson ratio of the raw-soil mechanism brick masonry were obtained. Meanwhile,the value determination methods of deformation modulus and poisson ratio of the raw-soil mechanism brick masonry were discussed and influences of different mixture in mortar on deformation modulus and poisson ratio were explored,which provides reference to unified standards in raw-soil materials.
