The Federal Highway Administration (FHWA) \u2013 Mechanically Stabilized Earth Walls and Reinforced Soil Slopes Design Guidelines and research published in Geotextiles and Geomembranes (Koerner, 2012) indicate that geogrid reinforcement greatly enhances […]<\/p>\n","protected":false},"author":1,"featured_media":1436,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[36],"tags":[243,239,285,290,291],"acf":[],"_links":{"self":[{"href":"https:\/\/www.lianyigeosyn.com\/cs\/wp-json\/wp\/v2\/posts\/1435"}],"collection":[{"href":"https:\/\/www.lianyigeosyn.com\/cs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.lianyigeosyn.com\/cs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.lianyigeosyn.com\/cs\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.lianyigeosyn.com\/cs\/wp-json\/wp\/v2\/comments?post=1435"}],"version-history":[{"count":0,"href":"https:\/\/www.lianyigeosyn.com\/cs\/wp-json\/wp\/v2\/posts\/1435\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.lianyigeosyn.com\/cs\/wp-json\/wp\/v2\/media\/1436"}],"wp:attachment":[{"href":"https:\/\/www.lianyigeosyn.com\/cs\/wp-json\/wp\/v2\/media?parent=1435"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.lianyigeosyn.com\/cs\/wp-json\/wp\/v2\/categories?post=1435"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lianyigeosyn.com\/cs\/wp-json\/wp\/v2\/tags?post=1435"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
