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。
Thermal power plant cooling tower on the foundation bearing capacity requirements are high, in the natural foundation bearing capacity can not meet the requirements of the superstructure, the general use of artificial methods to deal with the natural foundation. This paper introduces the design, construction and testing of the lime-soil compaction pile in the foundation treatment project of the cooling tower in the collapsible loess area through the engineering practice. It shows that the lime-soil compaction pile is used in the foundation engineering of the cooling tower in the collapsible loess area Technically feasible, the treated foundation bearing capacity and stability have been greatly improved.
