In this article, the seismic resistant effect of a new reinforcement measure on rockfill dams, the Composite Reinforcement, is investigated based on 1-g large-scale shaking table tests. A 1 m high rockfill dam, which is scaled from the Yele rockfill dam in China, is tested by inputting a series of motions designed from a realistic Wenchuan earthquake record. The model dam is divided into two sections, with one section representing a normal rockfill dam (RD) while the other section employing the Composite Reinforcement (composite reinforced rockfill dam (CRRD)). The seismic-resistant effect of the Composite Reinforcement is investigated by comparing the recorded dynamic response of the two dams, in terms of the peak acceleration amplification factor distribution along the dam core, the crest settlement, and the visualized failure pattern. Results show that the application of the Composite Reinforcement can effectively mitigate the seismically induced deformation of the rockfill dam by reducing the peak crest acceleration and residual crest settlement by 18% and 55%, respectively, when subjected to a 0.5 g input motion. The investigation of the captured failure pattern on the two dams further indicates the effective reinforcing effect of the Composite Reinforcement on preventing the sliding failures of rockfill materials in the top 20% height of the dam body. 相似文献

历史上俄罗斯多次出现"回归欧洲"还是"融入亚洲"的讨论和选择,但独特的地缘政治和经济环境决定了俄罗斯必须在欧亚之间起到有效的链接作用,欧亚经济一体化的进程也离不开俄罗斯的积极作为。俄罗斯在积极与欧洲发展合作的同时也要在亚洲扮演重要的角色。中俄边疆区域合作是中俄关系发展的主要组成部分,为使中俄关系保持持续和稳定的发展,就必须排除"中国威胁论"论调的干扰。 相似文献

By investigating the Tang-Song examples of widows remaining chastity or inviting a jiejiaofu (second husband) into the deceased husbands’ families, this article analyzes widows’ lives and their right to inherit their
deceased husbands’ family properties. The conclusion is that widows had only “rights of management,” but not the “possessive
right,” over their deceased husbands’ properties. Moreover, the qualities of widows’ lives in their in-law’s families depended
on their relationships with the deceased husbands’ brothers. When being treated unfairly, widows often resorted to “the power
of the maternal uncle” in order to defend their benefits.
