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土坝自修建以来遭受了多次地震，尤其是1985年9月19日的墨西哥地震。在其中几次地震中，获得了强震加速度、峰顶位移和沉降的测量结果。这项研究计划将利用这些信息来验证作为美国大坝地震反应研究结果而开发的数值分析技术。特别是，将检查连续地震在改变应力条件、运动响应和地基材料性能方面的影响。

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.
