抗震

So, it is necessary to study the characteristics of the slope protected by soil nailing under the earthquake.

所以，研究在地震作用下土钉支护边坡的动力分析及抗震设计方法是很有必要的。

This method can be used the first stage seismic design and analysis for the slope protected by soil nailing.

故这种方法可用于土钉支护边坡的第一阶段的抗震分析与设计。

The safe index of design performance is defined as the negative natural logarithm of structural failure probability in this paper.

因此，基于结构性能的抗震设计方法所要解决2004年12月Dec.2004的首要问题就是如何选择设计性能等级[1]。

After treatment and analysis of 150 domestic test data, probabilistic characteristics of displacement ductility factor of reinforced concrete frame columns and frames fits natural logarithm normal distribution and a functional expression is proposed by a statistical regression.

通过对国内150个钢筋混凝土框架柱和框架试验数据的整理和分析，得出位移延性系数的试验结果服从自然对数正态分布，并回归得到考虑多因素的位移延性系数经验公式，该公式可供钢筋混凝土框架结构抗震设计和评估参考。

Furthermore the expressions of nonelastic displacement response spectra were also given.

为研究其抗震设计方法，选择了35次地震，212组近断层地震记录作为统计样本，根据得到的平均弹性位移反应谱，给出了近断层地震设计弹性位移反应谱表达式，并在此基础上，给出了近断层地震设计非弹性位移反应谱计算公式。

These nonrestrictive units had concrete floors on an interior steel frame.

这些非抗震单元在内部为钢构架上是水泥地板。

Combined with results of theory,shaking table test and numerical simulation,dynamical interaction and aseismic capability of soil-structure system are studied and analyzed based on analysis of theory and calculation.

采用数值仿真试验进行结构地震反应的理论和计算分析，将理论分析结果、振动台试验结果和计算机仿真结果三者结合起来，研究和分析地基–结构动力相互作用及其抗震性能。

Based on the example of shahe reservoir, the text makes an analysis on circulation, management and environment and social economy development condition of the surrounding ecosystem. Then, the author carries on inquisition, data analysis and summary and makes calculation and demonstration of the safe stability of the dam ,and discusses the risking obviation and reinforcing technique. Finally, based on the existing research of sustainable development, experts" opinions and Mathematical Statistics analysis, the author brought forward an indication system suitable for reservoirs" sustainable development This system is made up of 4 first class indexes, 13 second class indexes, 38 foundational indexes. The 4 first class indexes are the dam safety evaluating index, the management index of reservoirs, the water ecosystem system stability index, the reservoirs construction effect index. The 13 second class indexes are the construction quality evaluating index, the dam running and management evaluating index, the flood control standard recheck index, the structure safety evaluating index, the anti- earthquake evaluating index, seepage safety evaluation index sign, the metal structure safety evaluating index, the engineering facility index, the management index, the water ecosystem system stability index, engineering effect index, the economic development index, the society development index.

本文以沙河水库为例，对其运行、管理及周围生态环境和社会经济发展状况进行调查，并将调查资料进行分析、归纳、总结；然后对水库大坝的安全稳定情况作出了简要的计算和论证，并讨论了水库的主要除险加固技术；最后在总结现有可持续发展研究的基础上，征集专家的意见，进行数理统计分析，提出了由4个一级指标、13个二级指标、38个基层指标组成的一套适合该水库可持续发展的指标体系。4个一级指标分别为：水库大坝运行安全综合评价指标、水库管理指标、水资源生态系统稳定性指标、水库建设效应指标；13个二级指标分别为：工程质量评价指标、大坝运行管理评价指标、防洪标准复核指标、结构安全评价指标、抗震安全评价指标、渗流安全评价指标、金属结构安全评价指标、工程设施指标、管理指标、水资源生态系统稳定性指标、工程效应指标、经济发展指标、社会发展指标。
