Post-Earthquake Investigation of Several Geosynthetic Reinforced Soil Retaining Walls and Slopes during Ji-Ji Earthquake of Taiwan

This chapter describes the application and seismic performance of geosynthetic- reinforced soil structures in Taiwan. Taiwan has a unique topography and geotechnical conditions that render a less conservative and more challenging design as compared to that of North America, Europe and Japan. The Ji-Ji (Chi-Chi) earthquake of 1999 gave an opportunity to examine the behavior of reinforced soil structures. The performance of several modular block reinforced soil retaining walls and reinforced slopes near the fault were evaluated. Reinforced structures performed better than un-reinforced soil retaining walls. The failure cases were highlighted and the cause of the failure was identified. The lack of seismic design consideration could be a major cause of failure. The compound failure mode, the inertia force of the blocks and the connection stiffness and strength relative to the large dynamic earth pressure were among the major items that warrant further design consideration.
