某在建600MW超临界机组刚性吊架生根加强方法研究

Study on Rootage Strengthening Method for Rigid Suspension Hanger of a under-construction 600 MW Supercritical Units

针对某600MW超临界在建机组在建设过程中出现刚性吊架生根预埋件漏埋的问题,提出采用钢板包梁加植筋生根的处理方法,但出现上部钢板变形过大的问题;为此对整个生根结构进行系统的有限元仿真和力学分析,比较不同补救措施的优劣性,并在此基础上提出安全、经济的生根方法,取得良好效果。

In view of unburied embedded parts of rootage of rigid suspension hanger in the construction of 600 MW supercritical units, the paper proposes to adopt the approach of steel plate wrapped beam plus bar planting. There is great deformation of top steel plate, so finite element simulation and mechanical analysis on the rootage structure is implemented and, merits and demerits of different remedial measures are pointed out, on the basis of which a safe and economic rootage method is present and favorable effects is achieved.
