This is part of Webinar series of iGrip (Initiative for Geotechincial Research & Innovative Practices) which is organized by Indian Institute of Technology, Gandhinagar on 8th, June, 2020. This is the lecture of the Geosynthetics Reinforced Soil Structures for Japan railway by Watanabe, K. This lecture describes the history of earth structure, development of Geosynthetics Reinforced Soil Structures for Japan railway, especially for high speed rail. 507 engineers (mainly Indian engineers) attended this lecture. The presenter asked an interesting question to all the audiences and asked them to answer by using the [Polling system] of Zoom.
Question: Answer in [Yes] (Truth) or [No] (false) to the following comment.
[Reinforced-soil method is an effective method to reduce earth pressure acting on the wall. Thanks to the reinforcement (geosynthetics or metal strips), the earth pressure usually does not act on the facing. The wall (facing) is used only for covering the backfill, preventing from local erosion and local failure]
229 (70%) audiences answered [Yes] (this sentence is true) and 99 (30%) audiences answered [No] (this sentence is wrong) to this question. Do you know if it is true or not??
