核电常规岛抗浮锚杆的选型探讨及应用

Application of anti-floating anchor in the conventional island of the nuclear power plant

核电常规岛结构是一种非常特殊且重要的工业结构,往往具有埋深深、地上部分压重不足、场地透水性差的特点,以上特点导致其局部抗浮验算很难通过。从经济性上讲,在局部设置抗浮锚杆是非常有意义的。简要分析了抗浮锚杆的设计要点,并以某核电常规岛结构抗浮设计为例,针对核电常规岛的锚杆选型给出了建议。

The conventional island structure of the nuclear power plant is a very special and important industrial structure,which is characterized by deep burial,insufficient weight on the ground,and poor site permeability.The above characteristics make it difficult to pass the partly anti-floating calculation.From an economic point of view,it is very necessary to install anti-floating anchor bolts locally.This paper briefly analyzes the design points of anti-floating anchor rods,and takes the anti-floating design of a nuclear power conventional island structure as an example to provide suggestions for the selection of anchor rods for nuclear power conventional islands.
