Performance of Existing Geosynthetic Reinforced Slopes During the Northridge-LA Earthquake of 17 Janaury 1994

9412803霍尔茨这个项目涉及恢复1994年1月1日北岭地震的易腐烂数据，因为它与土工合成加筋斜坡(GRS)在地震荷载下的性能有关。土工合成加筋土坡是指使用土工合成材料加固的土坡(如路堑)，以防止斜坡破坏(山体滑坡)。该项目涉及：(1)识别在北岭地震中遭受重大震动的土工合成加筋斜坡，(2)估计这些斜坡遭受的地面震动和任何地震前的斜坡运动，(3)从地面和空中拍摄斜坡，测量地面上的滑坡大小、头和边坎、地面加固模式，以及土样的收集，以及(4)估计滑坡量、移动距离和坡角，并尝试将土壤类型、坡角、加固类型、加固模式、适用的坡度方向和位移大小。***

9412803 Holtz This project involves the recovery of perishable data from the Northridge earthquake of January 1, 1994, as it relates to the performance of Geosynthetic Reinforced Slopes (GRS) subjected to seismic loading. Geosynthetic reinforced slopes are earth slopes (such as road cuttings) which are reinforced against slope failure (landslides) using geosynthetic materials. The project involves: (1) the identification of geosynthetic reinforced slopes which were subjected to substantial shaking by the Northridge earthquake, (2) the estimation of the ground shaking to which these slopes were subjected and any pre- earthquake movements of the slopes, (3) photographing the slopes from the ground and from the air and the measurement of landslide size, head and side scarps, and reinforcement patterns on the ground, and the collection of soil samples, and (4) the estimation of slide volumes, distances moved, and slope angles, and an attempt to correlate soil type, slope angle, type of reinforcement, reinforcement pattern, slope orientation and magnitude of displacement, where applicable. ***
