五皋垅水库导流围堰稳定性优化中混凝土楔形体的应用

Application of Concrete Wedge in Stability Optimization of Diversion Cofferdam of Wugaolong Reservoir

以位于安义县长均乡曹村的五皋垅水库工程为例,分析了混凝土楔形体在水库导流围堰中应用后可起到优化围堰开裂特征参数、优化堰体结构稳定系数等积极作用,并分为设置混凝土楔形体、传统加固处理等情况,对混凝土楔形体作用展开试验分析。结果表明,设置混凝土楔形体后可有效控制围堰开裂特征参数,减少导流渗漏,水库导流围堰堰体裂缝长度明显减小,安全系数显著提升,加固效果优异。

Taking the Wugaolong Reservoir Project in Cao village, Changjun Township, Anyi County County as an example, the application of concrete wedge in the diversion cofferdam of the reservoir can play an active role in optimizing the cracking characteristic parameters of the cofferdam and the structural stability coefficient of the cofferdam. Under three conditions of setting concrete wedge, setting concrete wedge and taking traditional treatment of reinforcement, the effect of concrete wedge is tested and analyzed. The results show that the concrete wedge can effectively control the characteristic parameters of the cofferdam cracking,reduce the diversion leakage, significantly reduce the length of the diversion cofferdam cracking, significantly improve the safety factor and achieve excellent reinforcement effect.
