［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。［关键词］机制生土砖砌体; 砂浆; 变形模量; 泊松比中图分类号：TU361 文献标识码：A 文章编号：1002-848X(2016)12-0067-06
Experimental study on deformation modulus and poisson ratio of rawsoil mechanism brick masonryWang Yihong, Liu Qiji, Zhong Jiqing, Zhang Kun（School of Civil Engineering, Chang′an University, Xi′an 710061, China）Abstract: 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.Keywords: raw-soil mechanism brick masonry; mortar; deformation modulus; poisson ratio
