| 摘 要： | 通过对大连港东部地区搬迁改造项目大开挖段监测数据的分析,阐述了软土地基上建立重力式水工护岸加载分级控制效果。利用理论计算与数据分析,将施工加荷与临塑荷载和塑性区深度发展为1/4地基宽度的荷载比较,找到了引起地基变形过大的原因。并通过重新调整加载量级与设计报警值,避免了地基塑性变形的进一步发展与剪切破坏,为类似软土地基上的重力式水工护岸工程积累了加荷分级与控制经验。

| Abstract: | According to the monitoring data analysis of the transformation and relocation project in the eastern region of Dalian port,the control effect of multi-stage loading of gravity revetment structure on soft foundation was expounded.Based on the theoretical calculation and data analysis,the construction load was compared with the critical edge pressure and the load when the critical plastic depth developed to 1/4 base width.Then the reason of subgrade deformation was found out.After adjusting the load magnitude and the alarm value ,the further deformation and shear failure of the foundation were prevented.The correlative engineering experience is accumulated and provided as reference for analogous projects. |
