| 摘 要： | 为确定合理的加固补强方案，应用有限差分程序FLAC对堂加2号土质古窑的稳定性进行评价。通过选择典型断面形状，将复杂的三维问题简化成为3种类型断面的平面问题。在合理选用土质模型参数的基础上，用强度折减法模拟分析了6种情形下可能的破坏模式和相应的安全系数，得出了最薄弱断面形状及相应的破坏模式。该模拟分析结果在现场施工时意外地得到了验证，为加固补强方案的确定提供了可靠依据。 |

| Abstract: | Dougaeri No.2 historical earthen kiln,located at North Kyushu of Japan,has complex shape and geometry.To determine a reasonable reinforcement design,finite different method code FLAC is employed to perform stability analysis.The complicated 3-D geometry is simplified into three types of 2-D problem.The shear strength reduction method is used to simulate the possible failure mode to obtain the corresponding factor of safety.The poorest geometry and dominated failure mode are presented clearly,and verified ac... |
