提出了一种新的方法，其中非连续变形分析（DDA）方法被用来估计历史地面运动的反分析独特的结构故障在考古遗址。在以色列的两个考古遗址进行了调查，使用这种新的方法和结果的研究砌体结构中选定的结构元素的位移演变。研究了结构的响应，直到初始失效点，其机制与现场观察到的机制相似。结构响应被发现是非常敏感的动态参数的加载函数，如振幅和频率。
An innovative approach is presented, in which the discontinuous deformation analysis (DDA) method is used to estimate historic ground motions by back analysis of unique structural failures in archaeological sites. Two archaeological sites in Israel are investigated using this new approach and results are presented in terms of displacement evolution of selected structural elements in the studied masonry structure. The response of the structure is studied up to the point of incipient failure, in a mechanism similar to the one observed in the field. Structural response is found to be very sensitive to dynamic parameters of the loading function such as amplitude and frequency.
