A large number of mining tailings pond were built in the upstream of the stope close neighbor to it,those distance is between 200 to *** tailings dam constructed at upstream is always in under-consolidated,and has low density and loose structure,the liquefied zone appears easily in the effect of mining blasting,and then the dam body is *** at one tailings dam of mining corporation,the horizontal vibration acceleration produced by mining blasting is field measured,then the measured data is adopted as the input ground vibration wave,and the response of tailing dam is analysed with dynamic finite element *** analysis result shows that the response of the latter accumulation dam is larger than that of initial dam,and there is no liquefied zone in tailing dam under blasting ***,it can be regarded that the current production blasting scale does not produce bad influence to the stability of dam *** provide a reference for the similar engineering in the future.

在土地监管中,往往存在用地变化数据的级级过滤、层层修改,导致上级监管部门难以掌握真实有效的数据,造成决策失误。针对这一问题,提出一种网络化土地监管数据库中数据疑似非法修改的检测方法:采用数据库日志分析实现捕获变化数据,通过分析土地监管中的业务流程数据,提取非法修改行为的流程数据特征构建规则库;对比变化数据与特征库,实现对疑似非法修改数据的识别和提取,并对确认非法修改的数据进行疑似用户的追踪。为了检验方法的可行性,开发实现了网络化土地监管数据库中数据疑似非法修改检测系统,并在各级监管单位采用集中式部署管理。系统运行结果表明,该方法可以实现疑似非法修改数据的检测,满足上级对下级数据真实性掌控的需求,有助于提高土地利用的监管效率。

西方经济学界将博弈分析方法推广到金融领域取得了理论成果，尤其以宏观金融博弈分析在２０世纪９０年代的最新发展为主要内容。完全信息动态博弈和不完全信息动态博弈两类模型，对货币政策的连贯性与可信度以及中央银行声誉做出了重新解释，货币政策目标、货币政策操作程序、中央银行独立性及政策透明度等热点问题在我国金融体制改革实践中的作用是至关重要的。
