石灰岩地区冷却塔地基处理

Foundation Treatment of Cooling Tower in Limestone Zone

对在石灰岩地区电厂冷却塔地基基础设计中存在的问题进行了讨论 ,提出了处理溶沟、溶槽、溶洞的原则 ,以及加密钻孔 ,采取加厚环基、淋水支柱几个基础连接成条基增大刚性等结构措施 ,加强验槽等地基处理方案 .这些措施 ,在工程实践中取得了较好的效果 。

The design problems of foundation treatment of cooling tower in limestone zone are discussed. The treatment principle of solution groove, solution channel, and solution cavern is put forward. Other schemes of appended drill hole, thickening of girdle foundation, joined base of leaching supporting post to footing beam,etc., are put forward too. These measures have acquired success, and ensured safe run of the cooling tower.
