项目摘要

Japanese castle's masonry walls were piled up with the independent stone block without using lime, and their techniques are very unique like Sori-curve or Sanngi-method at corner. So they are very important world heritage. But because of aging, many of them are very dangerous to the collapse.The results of this study are as follows.(1) On the vibration table, we made the model masonry walls of similarity ratio=1/10. From the vibration tests, it was made clear that the stability of masonry walls were effected by the angle of walls, and the deformation and the acceleration are amplified from the base to the top.(2) From the loading test at the shoulder of walls using the model masonry walls, it was made clear that the upper load should be located within the length of piling stone.(3) From the numerical experiment using FEM, it was made clear that the earthquake wave's amplitude was amplified, but the acceleration was reduced within the ground. But respectively, the amplitude and the acceleration were amplified within the masonry walls. There-fore, the top of walls is dangerous to the collapse during earthquake. And the stability of walls is effected mainly by the height or the angle, and the property of matters are not so effective.

日本城堡的砖石墙是用独立的石块堆积而成，不用石灰，其技术非常独特，如角落处的Sori曲线或Sanngi方法。因此，它们是非常重要的世界遗产。但由于老化，其中许多是非常危险的崩溃。(1)在振动台上制作相似比为1/10的砌体墙模型。振动试验表明，砌体墙的稳定性受墙体倾角的影响，变形和加速度从底部向顶部放大。(2)通过模型砌体墙的墙肩荷载试验，明确了上部荷载应位于桩长范围内。(3)通过有限元数值试验，可以清楚地看到，地震波的幅值被放大了，而地面内的加速度被减小了。但在砌体墙内，振幅和加速度分别被放大。因此，在地震作用下，墙顶有倒塌的危险。墙体的稳定性主要受墙体高度和墙体倾角的影响，而材料的性质对墙体的稳定性影响不大。
