1、用土工织物加固挡土墙软土地基的方法及体会中英文翻译WithgeotextilesreinforcedretainingwallmethodandexperienceofsoftsoilfoundationinbothChineseandEnglishtranslation1.引言1.Introduction土工织物又称土工聚合物，它具有高抗拉强度，耐久性、耐腐蚀性，质地柔韧，能与砂土很好地结合，组合成加筋土复合地基，有效地提高土的抗剪强度、抗拉性能，增强土体的整体性和连续性。对于其加固机理，早在20
2、世纪60年代，HenriVidal就用三轴试验发现了在砂土中加入少量纤维后，土体的抗剪强度可提高4倍以上的形象，近年来，我国岩土工作者也在试验室中证明了在砂土中加筋可有效地提高土体的地基承载力，减少地基竖向沉降量，有效地克服土体整体性差及连续性差的性能。由于加筋土具有以上的性能，且其价格低廉的特点，使其在工程中具有广泛的应用前景。Geotextiles,alsoknownasgeotechnicalpolymer,ithashightensilestrength,durability,corrosi
