Learning from the Mexican Earthquake of September 19, 1985 and Previous Earthquakes: Safety and Performance of Dams

墨西哥的El Infiernillo和La Villita土坝受到了 自建造以来，发生了许多地震，但特别是 1985年9月19日墨西哥地震 测量 强震加速度、峰值位移和沉降， 在几次地震中获得。 这个研究项目 将利用这些信息来验证数值分析技术 作为大坝地震反应研究的结果， 美国的 特别是，连续的影响 地震在改变应力状态、运动响应和 将对基础材料的性能进行检查。

El Infiernillo and La Villita earth dams in Mexico have been subjected to a number of earthquakes since their construction, but especially the Mexican earthquake of September 19, 1985. Measurements of strong-motion acceleration, crest displacements, and settlements were obtained during several of these earthquakes. This research program will utilize this information to verify numerical analysis techniques developed as a result of studies in the earthquake response of dams in the United States. In particular, the effects of successive earthquakes in changing the stress conitions, motion response, and performance of the foundation materials, will be examined.
