As with the above properties of reinforced soil and the characteristics of its low price, so the project has broad application prospects. Project Overview The proposed retaining wall using rubble retaining wall of gravity, the wall is 6 meters high, the bearing capacity of foundation soil required to 250kPa, while the basement geology from the top down as follows: ① clay to a thickness of to 2 meters saturated, soft plastic。加筋處理的方法為：首先對開挖至基底設(shè)計(jì)標(biāo)高并鋪一層 200mm 厚的碎石墊層，然后的其上鋪 1 層土工織物，再在其上 200 厚砂礫石，用黃砂找平后用壓路機(jī)壓實(shí)；第二層用裝砂石的土工織物袋鋪設(shè)，其空隙用礦渣填平，土工袋上鋪 100 厚的碎石，壓路機(jī)壓實(shí)。 二、施工程序?qū)咏钚Ч兄卮蟮挠绊懀┕r(shí)應(yīng)讓土工織物盡早處于受拉狀態(tài)，土工織物抗拉強(qiáng)度只有在
