文章介绍了红山嘴电厂二级电站前池改造时地基存在的问题,提出3种换填方案,针对各方案进行比较分析,尝试采用水泥稳定土进行地基换填。红山嘴电厂二级电站增效扩容改造工程实施时,发现前池地基存在大量的软弱土层,在对前池地基进行加固处理时,采用了水泥稳定土。文章对水泥稳定土换填施工操作过程做了详细介绍,对工程改造实施效果进行效益分析与评价。
This paper introduces the problems of foundations in the reconstruction of the front pool of the Second Power Station of Hongshanzui Power Plant, puts forward three kinds of replacement schemes, and makes comparative analysis of each scheme, trying to replace the ground with cement stabilized soil. During the implementation of the efficiency expansion and expansion project of the secondary power station of Hongshanzui Power Plant, a large amount of weak soil layer was found in the foundation of the forebay. When cementing the foundation of the forebay, the stabilized soil was used. This paper introduces the process of cement stabilized soil replacement filling operation in detail and carries out the benefit analysis and evaluation on the effect of the engineering reconstruction.
