1、(1)填方邊坡之整坡坡度不宜太陡岩盤線或原地面線地下水流向(2)填方邊坡避免填築於陡坡上2.填方邊坡填築於陡坡面易沿界面滑動一般路提填方地下水較不易匯積於坡面岩盤線或原地面線地下水流向(3)填方邊坡坡趾擋土牆應採高透水性(4)採用平台階段濾料層加強地下排水岩盤線或原地面線地下水流向平台階段濾料層(5)填方邊坡之斜坡夯實方法(6)填方邊坡之斜坡不易夯實極易導致浸潤帶之滑動(6)填方邊坡之斜坡不易夯實極易導致浸潤帶之滑動預防對策1採用斜坡夯實法填方邊坡之整坡坡度不宜太陡(6)填方邊坡之斜坡不易夯實極易導致浸潤帶之滑動

2、預防對策2採用平台階段濾料層加強地下排水岩盤線或原地面線地下水流向平台階段濾料層(6)填方邊坡之斜坡不易夯實極易導致浸潤帶之滑動預防對策3採用加勁護坡岩盤線或原地面線地下水流向平台階段濾料層(6)填方邊坡之斜坡不易夯實極易導致浸潤帶之滑動預防對策46.注意河岸沖刷之影響(7)必須防範浸潤帶之滑動(8)必須處理特殊滑動弱面(1)大量開挖必須預防泥岩解壓膨脹風化崩解挖方邊坡(2)避免挖斷順向坡坡腳挖方邊坡jEZauP0lG!cxS3oJ%ezU5qL(hCX7sN-jEZavQ1mG!cxS3oJ&fAU5qL(hC
