摘　　要：通过对同尺寸的单块素土坯及掺和麦秸秆的单块土坯的各向抗压试验获得了素土坯和掺和麦秸秆土坯的抗压强度及受力破坏形态,总结了单块土坯抗压试验的试验过程及试验现象。得到荷载—位移曲线后,评估掺和麦秸秆对土坯抗压承载能力的影响及得出了麦秸秆的最优掺量。掺和适量的麦秸秆能提高土坯的抗压强度及应变能力。从本试验研究得出的结果,为土坯砌体试验和土坯墙片试验提供基本力学性能数据。Through the compressive test of adobe and straw fiber adobe with same size, the compressive strength and failure mode of adobe and straw fiber adobe are obtained, at the same time, the process and phenomenon of the experiment are summarized. After the load - displacement curve is gained, the influence of the straw fiber on the adobe eompressive load - bearing capacity is assessed and the optimum usage of straw fiber is obtained. Blend of right amount straw fiber can improve the compressive strength and strain capacity of the adobe. These are the basic data for the adobe masonry and adobe wall experiments.
