【单选题】当采用“五点重合法”确定悬链线拱轴的拱轴系数m时,要求全拱有五点与下列哪种拱桥的恒载压力线重合()
【多选题】下列关于“累计折旧”科目表述不正确的有( )。
【简答题】如何用“五点重合法”确定空腹式悬链线拱的拱轴系数m?
【简答题】五点重合法是指:使拱轴线和压力线在:两个( )、( )和两个 l/4 点这五个位置重合,来求解悬链线方程的方法。
【单选题】为计算方便,对L<100m的空腹拱桥仍采用()作为拱轴线,一般采用“五点重合 法”来确定其拱轴系数值。
【单选题】If someone wants to confirm something, it means _____________.
A.
he wants to make sure of something
B.
he wants to rearrange something
【简答题】空腹式悬链线拱在用“五点重合法”确定拱轴系数m时,要求拱轴线与三铰拱的()保持五点重合。
【单选题】He wants to find someone with _______ he could discuss such questions.
【判断题】拱轴线在全拱有五点(拱顶、两拱脚、两l/4点)与其相应的三铰拱的恒载压力线重合,用此五点重合建立的拱轴线,称为五点重合法。
【单选题】If someone is retired and only wants to work at weekends with easy responsibilities like answering the telephone, where he or she should call to get more information for the position?
