摘　　要：依据南疆地区土坯的常用尺寸,参照砌体基本力学性能试验方法标准进行了土坯及土坯砌体、改性土坯砌体的抗压强度试验.分析了土坯、灰浆强度、砌筑质量和试验方法对土坯砌体抗压强度的影响,提出了抗压强度标准值的简化计算公式.试验结果表明,湿法制成的土坯抗压强度很低,掺和麦秸秆仍无改观,建议从土料的级配、添加改性剂和生产工艺方面提高土坯砌体抗压强度.According to the common sizes of adobe bricks in southern Xinjiang Uygur Autonomous Region and the test method codes for basic mechanical properties of masonry,the compressive strength tests on single adobe,adobe masonry specimens and modified ones were carried out.The influences of the strengths of adobe and grouting,masonry quality and test method on the compressive strength of adobe masonry were analyzed.A simplified formula for the compressive strength of standard values was proposed.The test results show that adobe made from mud has low strength whether or not straw was added.The compressive strength of adobe masonry may be improved by highlighting the soil gradation;modifying agent and production technology.
