摘　　要：自嵌固生土砌体结构作为一种新型砌体结构形式,由于其就地取材、绿色环保、建造快速且成本较低等特点,逐步受到国内外学者的重视和研究。本文针对作者研究团队提出的自嵌固改性生土砌体结构体系,采用数值分析的方法,重点研究了该类砌体墙体初始侧向刚度随墙体高宽比和竖向压应力的变化趋势,通过大量分析总结,提出了计算该类墙体初始侧向刚度计算公式,并与传统砌体侧向刚度计算公式进行对比分析。结果表明,针对自嵌固墙体,传统砌体抗侧刚度计算公式在墙体高宽比较小时,明显偏大,而本文提出的公式更适合用来计算该类墙体的初始侧向刚度。This research paper introduces an innovative masonry system utilizing interlocking earth blocks,which have garnered global interest for their accessibility,sustainability,and efficiency in construction.Our study employs a numerical analysis methodology to explore the behaviour of interlocking block design,particularly focusing on the relationship between initial lateral stiffness,height to width ratio(aspect ratio),and vertical compressive stress.After a comprehensive examination of the data,we have formulated a calculation model for the initial lateral stiffness of these interlocking block walls,as well as compared with the formulas used for traditional masonry walls.Our comparative analysis reveals that the conventional methods provide larger lateral stiffness values for walls with a reduced depth-width ratio.The formula we have developed in this paper is more accurate and suitable for assessing the initial lateral stiffness of interlocking block masonry systems,which helps us better predict and design with these blocks,making construction safer and more efficient.
