【正文】 按此方法施工時可使土工織物盡早形成波浪形被拉緊，使其在受荷初期發(fā)揮作用。其中粘土及淤泥質(zhì)土承載力為 70kPa,顯然地基要做加固處理。 ② leveled the tension at both ends。s in the 20th century, Henri Vidal on the use of triaxial tests found a small amount of fiber in the sand, the soil shear strength can improve the image of more than 4 times in recent years, China39。 ④ gravel layer, the thickness of the uneven distribution points, about 0 to meters, slightly dense。對于其加固機理，早在 20 世紀(jì) 60 年代， Henri Vidal 就用三軸試驗發(fā)現(xiàn)了在砂土中加入少量纖維后，土體的抗剪強度可提高 4倍以上的形象，近年來，我國巖土工作者也在試驗室中證明了在砂土中加筋可有 4 效地提高土體的地基承載力，減少地基豎向沉降量，有效地克服土體整體性差及連續(xù)性差的性能。 3 幾點體會 為達到加筋土的加固效果，必須對加筋土施工工藝、施工質(zhì)量進行嚴(yán)格控制： 一、土工織物應(yīng)預(yù)加初期應(yīng)力，且其端部應(yīng)有可靠的錨固，以發(fā)揮土工織物的抗拉強度，錨固愈牢固，承載力提高愈多，地基中的應(yīng)力分布愈均勻，土工織物端部的固定，靠端部折起鋪設(shè)長度來保證，把端部折起包裹砂體，以增加其 握裹力， 5 保證使用期間不被拔出。 。其上再重復(fù)鋪設(shè)土工織物 → 碎石 → 壓實，直到墊層的設(shè)計厚度，本工程墊層厚為 1 米，共 4 層土工織物，兩層袋裝砂石。 ④ 2 higher end of sand。 ② muddy soil, about 22 24 meters thick, saturated, mainly plastic flow, local soft plastic。s bearing capacity, reduce the vertical ground settlement, effectively overe the poor soil and continuity of overall poor performance. 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
