华能岳阳电厂二灰坝软基滑坡机理及加固技术

The soft soil landslides principle and reinforcement technique of second ash-dam of Yueyang Huaneng electrical power station

湖南华能岳阳电厂二灰坝位于16m厚的淤泥地基上,自1986年投产以来多次出现滑坡,严重影响岳阳电厂煤灰排放及生产作业安全。文章结合该滑坡处治工程,采用现场地质勘探、室内试验和数值计算相结合的研究方法,对管桩加固软基堤坝的理论及施工工艺进行了系统的研究。

Second-ash-dam of Yueyang Huaneng electrical power station is located on 16 m clay foundation. Since 1986, landslides always happened in the second-ash-dam, which interrupted the production. Combined with the soft soil reinforcement project in the Second-ash-dam of Yueyang Huaneng electrical power station, the theories and construction arts of soft soil reinforcement were studied comprehensively, adopting the research method of sites tests, laboratory tests, and numerical simulation.
