摘　　要：针对素土土坯墙体的抗侧承载力和变形能力影响因素,采用数理统计理论中的正交试验因素分析方法,对素土坯墙体的静力弹塑性有限元非线性数值模拟计算结果进行了对比分析。研究了素土坯墙体厚度、洞口尺寸和竖向载荷对墙体抗侧承载力和变形能力影响程度。结果表明:未开孔的素土坯墙体,墙体厚度和竖向压应力对墙体的极限位移和极限载荷的提高具有同等重要的程度;开孔的素土坯墙体,墙体厚度、竖向压应力和开孔大小,对墙体的变形能力和抗侧承载力的提高程度相比较,竖向压应力的影响较大。For the factors that influence the lateral resistance capacity and deformation ability of plain abode wall,the orthogonal test method in mathematical statistics theory was used for analyzing the nonlinear static elastic-plastic finite element numerical simulation of plain abode wall.The degree of thickness,hole size and vertical load of the wall impacting on lateral resistance capacity and deformation ability of plain adobe wall were studied.The results show that ① for the plain abode wall without hole,the wall thickness and vertical load have a great impact on the seismic performance;② for the plain abode wall with hole, compared with the degree of thickness, hole size and vertical load of the wall impacting on lateral resistance capacity and deformation ability of plain adobe wall, the vertical load has a great impact on the seismic performance.
