| 摘 要： | 膨胀土具有强胀缩性、多裂隙性和超固结性,是工程上一种难以处理的＂麻烦土＂或＂不老实土＂。笔者近年提出了将这种＂不老实土＂约束在土工袋中的处理方法,并通过大量的室内、现场试验研究,验证了该处理方法的有效性。现概述了膨胀土的基本特性和膨胀土的处理原则,着重介绍了土工袋处理膨胀土的基本原理。通过土工袋浸水变形和膨胀力等室内试验分析,验证了土工袋具有提高膨胀土的强度和限制其膨胀变形等作用特点。 |
| 关 键 词： | 膨胀土 土工袋 浸水变形试验 膨胀力试验 |

| Abstract: | Expansive soil is a kind of "trouble" soil which is not easy to be treated in engineering, as it has the characteristics of strong swell-shrink,developing fissures and over consolidation. A method of reinforcing expansive soil with soilbags had been proposed and verified the availa-bility by laboratory and field tests. This paper summarized the basic characteristics and the treatment principle of expansive soil and introduced the principle of reinforcing expansive soil with soilbags. The wetting deformation and swelling force experiments were carried out on soilhags filled with expensive soil,verified the effectiveness of soilhags to enhance the strength and restrict the swelling deformation of expansive soil. |
