求翻译:As the lower end of the PT bar is pressing against a flat concrete surface, there is no need to use a "dome nut" or a spherical nut because it is more expansive than a flat nut. Moreover, if the PT bar needs to be prestressed to a high load (say 70% of the UTS, about 580KN), then the concrete underneath the bearing pla是什么意思?

PT酒吧下端按对一个单位的混凝土表面,有没有必要使用“圆顶螺母或球形螺母,因为它是较平坦的螺母膨胀。此外,如果需要预应力高负荷(约580kn说70%的UTS)PT酒吧,那么下面的承压板的具体需要,要加强与“反爆破加固”(防爆筋)。如果你能提供强度混凝土和预应力在PT栏的信息,我们可以产生一个典型的图形显示反爆破加固。
