basement geology from the top down as follows: ① clay to a thickness of to 2 meters saturated, soft plastic。 ③ center 3 fill sand。加筋處理的方法為:首先對(duì)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)。 結(jié)束語(yǔ) 土工織物加筋墊層加固軟土地基是一種行之有效的、經(jīng)濟(jì)合理、安全可靠、簡(jiǎn)單易行的方法,但目前有關(guān)文獻(xiàn)介紹的僅是定性的、經(jīng)驗(yàn)的成分較多,尚缺乏嚴(yán)謹(jǐn)?shù)睦碚撚?jì)算公式、可靠充分的測(cè)試數(shù)據(jù)來加以說明,這些還有待理論工作者和廣大工程技術(shù)人員的不斷探索。 二、施工程序?qū)咏钚Ч兄卮蟮挠绊?,施工時(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)度只有在變形時(shí)才得以發(fā)揮,所以施工時(shí)不允許土工織物發(fā)生折皺,把土工織物盡可能拉平拉緊。由于加筋土具有以上的性能,且其價(jià)格低廉的特點(diǎn),使其在工程中 具有廣泛的應(yīng)用前景。 ⑤ weathered sandstone. Including clay and silty soil bearing capacity is 70kPa, obviously do foundation reinforcement. Enhanced Treatment of reinforced foundation cushion Reinforcement replacement method can be used for sand and gravel used for soil treatment, but due to loose bedding, based on past experience, with a gravel mat to treat a large settlement of the foundation always exist, even the characteristics of poor, often resulting in cracks in the superstructure, differential settlement of the image, this works for 6meterhigh rubble retaining walls, height and large, and because the walls 2 are 3 meters high wall, if there is differential settlement of retaining walls, cracks, will result in more serious consequences and thus should be used on the cushion reinforcement through economic and technical analysis, decide on the sa
