| 摘 要： | 提出了多种工程措施 ,以提高路堤下软基土工织物的加筋效果 ,这些措施是 :( 1 )选择堤底宽度较小的工程 ,避开加筋垫层尺寸效应的不利影响 ;( 2 )采用预应变加筋法 ;( 3)堤身填土要有一定的塑性 ,避免脆性破坏 ;( 4 )采用应变法确定织物的允许抗拉强度。这些措施在工程中极易实施并且不需大量增加工程造价 ,是经济且显效的措施 |
| 关 键 词： | 道路工程 土工织物 预应变加筋法 加筋 软基 尺寸效应 加筋机理 |

| Abstract: | Multiple measures to improve effect of soft cohesive subsoil reinforced by geotextile under embankment are proposed in this paper as follows:(1)Select a embankment engineering with shorter base; (2)Using prestrained reinforced method; (3)Embankment fill should have some plasticity and avoid brittle failure; (4)Using strain method to determine allowable tensile strength of geotextile. These measures are very easy to implement and don't require increasing of a large number of cost. |
| Keywords: | road engineering geotextile prestrain reinforced method reinforcement soft clay ground dimension effect reinforced mechanism |
