摘要
针对重力坝坝体中存在薄弱层面影响坝体结构安全,以龙滩大坝为例,选取9条薄弱层面,采用非线性有限元法计算获得的应力结果分析各层面抗滑稳定可靠度,并计算了层面体系可靠度。结果表明,该方法合理可靠,可供借鉴。
According to the effect of layer of weaknesses of gravity dam on the structural safety of dam, taking the Longtan dam for an example, selecting nine layers of weakness, reliability of stable against sliding of layers are analyzed and the system reliability of later is calculated by using the stress result, which is calculated by the nonlinear FEM. The results showed that the proposed method is reasonable and reliable and can be used for reference.
