- Artificial ground freezing technique that has been used successfully and frequently in shanghai is an economical and reliable method to dig metro tunnels in soft soil
摘要人工冻结施工技术是软土中地铁隧道开挖的一种经济可靠的方法，在上海地区得到了多次成功应用。 - For example , on the survey report of wu yi civic square of changsha , we can draw the following conclusion : the square lacks arbors . it looks like the ignorance of the designer , but through analysing carefully , in fact , the technology of planting on the artificial ground and construction " s roof is inadequate . another example , the behavior and psychological characteristics of people in the open space of city , which are often ignored by the designer , and are very important in creating two kinds of basic behavior space : facility for rest and space for walking
本文着重对休闲广场设计中的难点问题作了阐述，例如立体绿化中的技术问题，通过调查报告，可以得出长沙市五一市民广场绿化中大树偏少的结论，从表面看似乎是设计师的问题，但通过仔细分析，实际上还是立体种植的技术手段跟不上；又如城市公共空间中人的行为心理特征，这是目前设计实践中容易忽视的问题。 - Obviously , the artificial ground motions used for structural time history analysis should well coincide with multi - damping - ratio - spectra . based on the comparison of the conventional algorithms for multi - objective optimization and genetic algorithms , a method for the simulation of multi - damping - ratio - spectra is proposed in the thesis which combines the multi - objective optimization algorithms and genetic algorithms . the program corresponding to the method is also developed and the method is proved to be feasible and convenient by an example at the end of the thesis
本文通过分析多目标优化问题的解的意义和常用解法，在比较现有的几种常用优化算法的基础上，选用遗传算法这种自适应全局优化概率搜寻算法作为本文的搜寻方法，将其与多目标优化理论有机地结合在一起，形成多目标遗传算法，并将其引入地震动仿真，形成基于遗传算法拟合多阻尼比反应谱的地震动仿真程序。 - Artificial ground motions , for their optional and statistic properties , are regarded as an important form of input for structural time history analysis in contrast to the actual records . present simulation methods which are mostly derived from spectra - compatible technique do well suit for single - damping - ratio - spectra simulation , but the simulation precision is not satisfactory when the spectrum is n ' t the object spectrum
目前常用的反应谱拟合技术能对给定单一阻尼比反应谱进行较好的拟合，但在目标谱以外其它阻尼比反应谱的拟合上有较大误差，这就是反应谱拟合技术中存在的多阻尼比反应谱拟合问题。
