A.钢板桩围堰

B.双壁钢围堰

C.单壁钢围堰

D.钢套箱围堰

答案

参考答案:D

解析:此题主要考察考生对深水承台施工的知识掌握。根据教材表述,钢板桩围堰的抗水流及抗冲刷能力差,适用于在流速较小、水位较低、承台较浅、河床地质透水性弱的地层使用;单壁钢围堰、双壁钢围堰适用于在流速较大、水位较深、承台较浅的地层;吊箱围堰适用于高桩承台,吊箱围堰是由钢板、加劲肋焊成的侧、底板和支撑体系拼成的带底板的盒式水密结构。通过分析考试说明,每题的备选项中只有1个是最符合题意,那本题的正确项是"D.钢套箱围堰"。

after storms. We will realize our dreams  5   last if we do our best. Cooperation(合作) is also necessary.

can't be   6   by one person alone.    7   is like a small part of a machine. If one part isn't   8 , the machine
can not work well. It's hard for a person who is away from the society to have a deep understanding of
the world. Cooperation is becoming one of     9  aways for people living in the developing society. As a
