摘要
某电厂#7、#8机组(2×660MW)工程间冷塔工程地基处于非均匀性的湿陷性黄土且其中混有大量1.0m以上的大漂石及各种岩性的薄层或透镜体的地质,地基处理采用碎石碾压垫层换填处理(换填厚度6m),碎石碾压垫层下超挖部分采用C10毛石混凝土换填至碎石垫层底的处理方法,满足了设计地基承载力的要求,取得了较好的综合经济效益。
The indirect cooling tower foundation of #7、#8 unit(2×660MW)engineering of certain power plant,was situated in the geology of non-uniformity collapsible loess and which was mixed with a large number of big boulder(more than 1.0m)and varieties of lithology thin layer or lens.The breakstone rolling cushion replacement filling method was used in foundation treatment(the thickness of replacement filling was 6m),the overbreak part under breakstone rolling cushion was replaced and filled till the bottom of breakstone cushion with C10 rubble concrete,to meet the requirement of foundation bearing capacity.It achieved good overall economic efficiency.
