| 摘 要： | 结合某地下车库顶板出现开裂问题,首先进行现场调研,根据裂缝出现的位置和形状得知,裂缝的产生可能与后浇带未封闭前在局部挡土墙进行回填土的回填有关.然后借助ANSYS有限元软件模拟不平衡回填状态下回填土荷载对顶板开裂的影响,并对比不同的回填顺序下车库顶板的应力云图分布.最后得出本工程事故中,车库顶板的开裂与后浇带未封闭前在挡土墙外的基坑进行回填土的回填有关.

| Abstract: | The paper makes a study of the specific projects and Huangdao Harbor engineering accidents with a support of an on-site investigation carried out.Firstly,it is proved that the accidents,according to the location and morphology of cracks,may be caused by the local backfill which is not closed in front of the back strip retaining walls.Secondly,by using ANSYS finite element software to simulate the garage roof position and orientation of cracks,a comparison with different backfill order and the different of stress on roof is made.Finally, a conclusion is drawn that garage roof cracks are troubled with the pit backfills outside retaining walls. |
