深层搅拌桩在青岛西海岸的应用研究

Application Research of Deep Mixing Pile in Western Coast of Qingdao China Oceanic University Yu Liang

从工程实例中,观察到青岛西海岸地区深层搅拌桩复合地基承载力的设计值与实测值存在较大的差值,分析其原因,发现计算复合地基承载力公式中,计算桩身强度折减系数(η)的取值范围偏小,通过反复计算、比较、分析,得出适合该区取值范围,为在青岛西海岸的地层组合条件下,设计深层搅拌桩复合地基承载力提供了可靠依据。

By the project example, it observes there is great difference between the designed value and actually measured value of the bearing capacity of deep mixing pile compoundfoundation. After analyzes the reason, it finds, in the calculation formula of the compound foundation's bearing capacity, the value selecting range of the reduction factor (η) for calculation of the pile body's intensity is on the small side. After repeatedly calculation, contrast and analysis, it gets the value selecting range applicable to this area, which provides a reliable basis for designing the bearing capacity of the deep mixing pile compound foundation under the condition of the stratum combination of Qingdao western coast.
