摘要
土工织物的蠕变现象十分明显 ,它的蠕变性质和许多因素有关。其中有无土侧限条件时 ,蠕变性能不一样。提交了 2种典型土工织物的侧限拉伸蠕变试验结果 ,分析在不同的荷载水平和上覆土压力限制下土工织物蠕变性能的变化 ,反映出土工织物在砂土中拉伸模量和抗拉强度随着上覆压力的增加而提高 ,蠕变应变和蠕变系数显著减小。
Creep is an important property of geosynthetics for its application in any permanent reinforced structures. The creep behaviour of geotextiles which is affected by different factors reacts differently under confined conditions and unconfined conditions. This paper analyse the load extension of woven and non-woven geotextiles that are confined in sand,the results showed that the modulus of extension and tensile strength of geotextile has increased and the strain and coefficient of creep has decreased with the improvement of the confined stress.
