摘要
火力发电厂冷却塔对地基的承载力要求较高,在天然地基承载力不能满足上部结构要求时,一般要采用人工方法对天然地基进行处理。本文通过工程实际,介绍了湿陷性黄土地区火力发电厂冷却塔地基处理工程中灰土挤密桩的设计、施工、检测,表明了灰土挤密桩在加固湿陷性黄土地区冷却塔地基工程中技术上是可行的,处理后的地基承载力和稳定性都得到了较大的提高。
The cooling tower for fossil-fuelled power plant has a high requirement for the ground bearing capacity. When the bearing capacity of natural foundation cannot meet the design requirement, a ground treatment usually can be taken to strengthen it. From the practical engineering, the design, construction, and detection of the lime soil pile to strengthen the collapsible loess ground are introduced in this paper. The results show that this method is feasible technically and can satisfy the requirement of collapsible loess ground, and the bearing capacity and stabilitv of the ground are raised greatly.
