| 中文摘要:某建筑建成不久，底层填充墙及基础梁就产生了开裂，开裂原因为桩基承载力达不到设计要求、采取的基础梁加大补强方案因地基土固结而失效、淤泥固结产生的负摩阻力加剧了桩基下沉等，在原因分析后采用了加大基础梁截面尺寸、并在基础梁下增设锚杆式静压桩进行补强，有效地修复了裂缝，取得了预期效果。 |

| Abstract:Cracks were found in the bottom filled wall and foundation beam of a building because the bearing capacity of pile foundation could not meet the design requirements, foundation beam+reinforcement scheme failed with foundation soil consolidation and negative friction of silt consolidation caused pile foundation subsidence. After analysis on these problems, cracks were filled by enlarging the size of foundation beam section, and by the reinforcement with anchoring static pressure piles. |
