地处东海之滨的杭州湾北岸,属淤泥质潮汐海滩,近年来潮沟逐渐逼近,岸线明显冲刷后退,滩地表层的褐色粉砂壤土,抗波浪冲蚀能力极差,为确保边坡的稳定,奉贤县海塘管理所汪相益同志来稿称:近年来他们采用土工织物作滤层,以代替传通的砂砾垫层,在距芦潮港测站10公里,金山咀测站87公里一段工程内,共铺设了土工织物8665m~2,工程总长度为963米。工程完成后,经受涨落潮的考验,整个护岸工程情况良好,既控制了被保护的土体流失,又避免
Located in the north bank of the Hangzhou Bay on the coast of the East China Sea, it is a silt tidal beach. In recent years, the tidal ditch gradually approaches and the coastline recedes obviously. The brown silty loam on the beach surface is extremely poor in erosion resistance. In order to ensure the stability of the slope In the recent years, they used geotextiles as a filter layer to replace the gravel cushion in the transmission. Within a section of 87 km from Jinshanzui Station, 10 km away from Luchaogang Station, Total laying of geotextile 8665m ~ 2, the total length of 963 meters. After completion of the project, withstand the test of ups and downs, the entire bank protection works in good condition, not only control the loss of protected soil, but also to avoid
