摘要: 主要从地下厂房岩壁吊车梁结构应力、变形等方面介绍了溧阳抽水蓄能电站地下厂房岩壁梁监测设计及安全监测成果。监测资料分析结果表明,目前岩壁梁支护结构应力、围岩变形较大但已趋于稳定,混凝土结构应力与结合缝张开较小,岩壁梁处于逐步稳定的工作状态。由于溧阳抽蓄工程地质条件在国内外同类工程中的特殊性与复杂性,因此,其对于以后同类工程地下厂房岩壁吊车梁监测设计、施工和监测资料分析等具有特殊的意义与重要参考价值。

Abstract: This paper introduced the monitoring design and safety monitoring results of crane beam in underground powerhouse of Liyang pumped storage power station, mainly about the structural stress and deformation. The results of monitoring data analysis show that, at present, the stress of crane beam supporting structure and the deformation of surrounding rock are large but stable; the stress and crack on concrete structure are small; crane beam is in a gradually stable working state. Because of the particularity and complexity of the engineering geological condition of Liyang pumped storage power station, with regards to the monitoring design of crane beam in underground powerhouse, construction and monitoring data analysis, it is worthy of reference.
