土工织物施工期内强力保持浅析

Analysis of geotextile strength retention situation during construction

通过对无纺布老化性能、於堵性能及塑料排水板工后性状的研究,对湛江某港区陆域形成围堰工程使用的充填砂袋为样本进行研究,3个月施工期后,对处于围堰不同位置的聚丙烯编织土工布进行强力指标试验。通过分析数据发现,若要满足强力指标保持率的要求可采取浸入水中一定深度进行保护,也可结合地区年日照、辐射量等气候条件推算光样老化影响。

In this paper,according to the research of aging property,colmation performance and the performance of plastic drainage plate after construction for non-woven geotextile,the filling sand bags used in Zhanjiang Port land formation cofferdam were studied as research subjects.After three months,the strength index test of polypropylene non-woven geotextile at different locations of the cofferdam was carried out.The data analysis shows that water can protect geotextile from aging.According to regional annual sunshine,radiation and the other climatic conditions,the coefficient of optical oxygen aging effects can be calculated.
