摘要： 取水隧洞是压水堆核电站重要的组成部分，也是核电站安全运营的重要影响因素。采用经典的弹塑性理论，对拟采用的取水隧洞初步设计方案进行理论比选分析。计算获得的应力场、位移场及塑性区对最终方案的确定及后期的支护结构设计有一定的参考价值。

Abstract: Water tunnel is an important part of the pressurized water reactor nuclear power plant, also a key factor in affecting its safe operation. Preliminary scheme comparison of water tunnel is completed with the classical elastic\|plastic theory. Through above analysis, the calculated stress field, displacement field and plastic zone have some reference value for determination of the final scheme and post design of the supporting structure.
