某拟建输水隧洞在III类围岩中采用开敞式TbM开挖,喷混凝土作为初期支护,钢筋混凝土管片作为衬砌,承担110m水头的内水压力和200m水头的外水压力,水荷载较大。在考虑管片之间及外包结构的接触关系、管片配筋和混凝土联合受力的条件下,采用有限元法模拟分析了管片衬砌在水荷载下的应力和变形特性,认为外水压力是管片衬砌设计的控制性荷载,从而提出了可供结构设计计算参考的管片模型简化处理方式。研究认为,在本文的围岩、支护、水荷载条件下,将钢筋混凝土管片作为隧洞衬砌是可行的。

The complete and incomplete fusion cross sections for ^(6)Li+^(209)bi were measured using the in-beamγ-ray method around the Coulomb *** cross sections of(deuteron captured)incomplete fusion(ICf)products were re-quantified experimentally for this reaction *** results reveal that the ICf cross section is equivalent to that of complete fusion(Cf)above the Coulomb barrier and dominant near or below the Coulomb barrier.A theoretical calculation based on the continuum discretized coupled channel(CDCC)method was performed for the aforementioned Cf and ICf cross sections;the result is consistent with the *** universal fusion function(uff)was also compared with the measured Cf cross section for different barrier parameters,demonstrating that the Cf suppression factor is significantly influenced by the choice of potential,which can reflect both dynamic and static effects of breakup on the fusion process.
