摘要
采用三维有限元技术对南水北调中线工程中大型预应力混凝土渡槽的预应力施加程序进行了优化研究 ,提出了合理的预应力施加方案 ,该方案使渡槽结构在施工期能更好地满足应力、变形的要求。
Applying the three dimensional finite element method, the process of prestressed loading on one large concrete flume in the diversion project from South to North of Central line is optimized. The flume structure can well satisfy the requirement of stress and deformation during construction period.
