［摘要］為研究一種不使用砂漿砌筑而是通過塊材間機械咬合作用連接的自嵌固生土磚墻的抗震性能，設(shè)計制作了兩片帶構(gòu)造柱與兩片無構(gòu)造柱的自嵌固生土磚墻試件，并對其進行低周反復荷載試驗。分析了試件的破環(huán)特征、極限承載力、滯回曲線和骨架曲線等力學性能。結(jié)果表明：構(gòu)造柱可以顯著改善自嵌固生土磚墻的抗震性能，表現(xiàn)在墻體開裂荷載、極限承載力、變形能力、耗能能力和整體性的提高。基于試驗結(jié)果和分析，結(jié)合現(xiàn)行《砌體結(jié)構(gòu)設(shè)計規(guī)范》（GB 50003—2010）中的砌塊墻體抗剪承載力計算方法，提出自嵌固生土磚墻的抗剪承載力計算公式，該公式的抗剪承載力計算值與試驗值吻合較好。

Abstract:In order to study the seismic performance of interlocking compressed earth block walls without mortar masonry connected by mechanical biting between blocks, two specimens of interlocking compressed earth block walls with constructional columns and two specimens of interlocking compressed earth block walls without constructional columns were designed and fabricated, and the low-cycle repeated load tests were conducted. The failure characteristics, ultimate bearing capacity, hysteresis curve and skeleton curve of the specimens were analyzed. The results show that the seismic performance of the walls can be significantly improved by the constructional column, which manifests in the improvement of cracking load, ultimate bearing capacity, deformation capacity, energy dissipation capacity and integrity of the wall. Based on the test results and analysis, combined with the calculation method of the shear capacity of the block wall in the current Masonry structural design code（GB 50003—2010）, a formula for calculating the shear capacity of the interlocking compressed earth block wall was proposed. The calculated value of the shear capacity of the formula is in good agreement with the experimental value.
