问题 单项选择题

某水利枢纽工程主坝坝高97m,坝顶长1020m,坝型为沥青混凝土心墙堆石坝,水库库容为1.52亿m3。枢纽所在地的地震动峰值加速度为0.05g,按《水利水电工程地质勘察规范》(GB50487—2008)规定,该工程()。

A.应进行专门的地震危险性分析

B.应进行地震动参数复核

C.应进行地震动参数确定

D.可按现行《中国地震动参数区划图》(GB18306—2001)确定地震动参数

答案

参考答案:D

解析:《水利水电工程地质勘察规范》(GB50287—-99)规定,工程场地地震基本烈度和地震危险性分析应根据工程的重要性和地区的地震地质条件,按下列规定进行。①坝高大于200m或库容大于10×109m3的大型工程或地震基本烈度为7度及以上地区的坝高大于150m的大型工程,应进行专门的地震危险性分析;②其他大型工程可按现行《中国地震烈度区划图(1990)》确定地震基本烈度。对地震基本烈度为7度及以上地区的坝高为100~150m的工程,当历史地震资料较少时,应进行地震基本烈度复核;③地震危险性分析应包括工程使用期限内不同超越概率水平下坝、库区可能遭受的地震烈度,坝址基岩地震峰值水平加速度及反应谱等地震动参数,以及合成基岩地震动时程。根据该水利枢纽工程的条件,无需就行专门的地震危险性分析和地震动参数复核,可以按现行《中国地震动参数区划图》(GB18306—2001)确定地震动参数。

阅读理解

任务型阅读:根据短文内容,完成下列任务。

                                                                 

     Jackie Chan born on April 7, 1954, in Hong Kong, China. His parents called him "Chan Kong sang", which

     At first, Jackie's family lived at the French Embassy (大使馆). His father was a cook, and his mother was

a housekeeper. When Jackie was seven years old, his family moved to Australia. His father got a job at the

American Embassy. Later back in Hong Kong, Jackie's father sent him to the China Drama Academy (中国戏

剧学院). The students there practiced kung fu and learned how to do stunts (特级表演).

     When Jackie was 17, he began to do dangerous stunts for films. In the early 1980s, Jackie went to

Hollywood, but he wasn't very successful. He went on to make films in Hong Kong and had great success.

Finally, Jackie Chan became famous in the United States. Today, Jackie Chan has both Chinese and American

fans, and his films make millions of dollars.

任务一:
