| 摘 要： | 本文通过对纤维加筋粘性土的剪切试验，拉伸试验，断裂韧度测定试验和水力壁裂试验等系统的试验的研究。指出纤维加筋能显著提高粘性土的抗剪强度，增加其在拉应力作用下的塑性和韧性。由纤维加筋粘性土在受拉时表现为裂而断，这就能防止土工建筑物由于开裂和渗透而造成的整体破坏，增强了其自愈的能力。

| Abstract: | A series of tests including shear test, tension test, fracture toughness test and hydraulic fracturing test has been performed for fiber-reinforced cohesive soil. The test results show that in comparison with ordinary cohesive soil, fiber-reinforced cohesive soil has higher shear strength, toughness, plasticity and possesses self-seaming ability. This kind of soil may be cracked but will not breaks under tension, thus preventing earth structures from complete failure. |
