【摘要】 大坝是一种特殊建筑物,及时准确地了解大坝工作性态,确保其安全极为重要。除险加固前后的性态分析,是研究加固措施是否有效的重要手段。本文以大坝除险加固为背景,对大坝安全监测方法进行系统研究,将加固前后数据作为一个系列,对加固前的监测数据采用免记忆推算法,逐步消除其对加固后的数据的影响。以山东某土坝为例,分别对应力和位移监测资料进行分析,研究其加固措施的效果,得出加固前的观测数据对加固后应力和位移的影响规律,给出了加固后监测数学模型。更多还原

【Abstract】 Dam is a kind of special buildings. It is very important to the safety of dam. The special natureof the decision must be timely and accurate understanding of dam behavior. In this paper,with the back-ground of dam,dam safety monitoring method has conducted the system research. The before and after rein-forcement data is looked as a series of data. Free memory algorithm has been given to deal with the moni-toring data before consolidation to eliminate its effects on the data after reinforcement gradually. A dam InShandong Province is looked as an example. The reinforcement effect is studied. The law of previous obser-vations how to affect stress and displacement law has got. The displacement and stress monitoring modelwere put forward respectively.更多还原
