摘要
考虑冻土流变、冻结壁卸载状态、冻结壁与周围土层共同作用等因素,建立了冻结壁变形的解析解。针对同一工程实例,分别采用理论分析与数值模拟两种方法,深入分析了深埋冻结壁的变形特性,计算结果与现场实测结果基本一致,较好地反映了实际情况。
Taking into account of the rheological property of forzen soils, the uninstall state of forzen wall, forzen wall acting with surrounding ground, etc, the analytical equation of forzen wall deformation is founded. Aiming at the same engineering example, the authors analyse the deformation characteristics of deep-buried frozen wall by theory analysis and numerical simulation. The results are in accord with scene survey and reflects actual status.
