问题 单项选择题

结构面直剪试验的主要目的是测定()的抗剪强度参数和剪应力与剪位移关系曲线,研究其受剪切荷载时的变形特性和破坏规律,为坝基、边坡、地下洞室岩体变形稳定分析提供抗剪参数。

A.混凝土与岩石接触面

B.节理面

C.层面

D.软弱结构面

答案

参考答案:D

解析:岩体的稳定性往往取决于其中的结构面,尤其是软弱结构面的性质,在某些情况下,研究软弱结构面的抗剪强度比研究混凝土与岩体之间的抗剪强度更为重要。

In the past few decades, the popular belief in the area of organizational behavior and psychology has been that    小题1:    workers are better workers. However, new research at the University of Alberta shows that sad workers are more    小题2:    .
Psychologist Dr. Robert Sinclair recently conducted a series of four studies 小题3:   the effects of experimentally induced ( 诱发的 ) happiness versus sadness on work    小题4:     by asking the participants to build circuit boards. In the first study, sad people committed    小题5:     few errors than did happy people, but there was no difference in the number of boards    小题6:    .
In similar studies Sinclair found the same results along with the evidence that happy people might not     小题7:    as much energy to the task in order to maintain their happy moods ---- they considered that task as something that might detract from their     小题8:    feelings.
These findings are not surprising, said Sinclair, since there has been a growing body of literature in the area of social psychology     小题9:   that sad moods lead to more calm lengthy intent consideration and often, more thought or accurate judgments. So it’s important for organizations to take into account the    小题10:  of their employees. It seems it could be beneficial to creating situations that lead people to believe that performing their jobs will cause them to feel good.
