地下室底板受力分析的FLAC数值模拟

On FLAC numeric simulation of stressed analysis of foundation slabs

介绍了FLAC数值模拟的基本原理,针对成都某高层建筑地下室底板变形开裂事故,利用FLAC数值模拟地下室底板在无顶板、有顶板无覆土、有顶板加覆土条件下的受力变形情况,揭示了该高层建筑地下室底板开裂的原因,并提出了合理的加固处理措施。

The paper introduces the basic principle for the FLAC numeric simulation, against high-rise building of foundation slab deformation crack accident in Chengdu, adopts FLAC numeric simulation for the stressed deformation of the foundation slabs with the conditions of without the apical plate, with the apical plate and without earthing, and with the apical plate and the earthing, and discloses the reasons for the slab cracks of the foundation in high-rise buildings, and points out the reasonable intensification treatment measures.
