| 摘 要： | 通过有限元分析程序，考虑两种墙厚、五种上部墙体正应力对局压承载力的影响，分别按柔性垫上梁宽范围内直接均布作用、进深梁上均布作用两种荷载类型进行空间有限元分析，得出了在不同荷载作用下，柔性垫梁下砌体局压应力的分布规律，比较了两种荷载下砌体内局压峰值应力的关系，建立了梁端设柔性垫梁的砌体局压承载力计算公式。同时，通过对比计算，比较了相同避压条件下，采用不同结构构造对局压承载力计算值的影响。

| Abstract: | By means of finite element analysis program, the local compression stress of masonry structure on flexible pad-stone was analyzed, in which two thick walls, five kinds of direct stress and two local load cases had been taken into account. The distributed law of local compression stress at two local load cases was given and compared with each other. A bearing capacity calculating method of local compression for masonry structure on flexible pad-stone was built. Meanwhile, comparative analysis of the bearing capacity of local compression for masonry structure that has different structure construction was given. |
