ABSTRACT
The paper presents the bearing ratio behavior of sand overlying clay with two woven and two non-woven treated coir geotextiles at the interface. The chemicals such as p-aminophenol, sodium periodate and sodium hydroxide were used to treat the coir geotextiles. The results indicated that the unsoaked/soaked bearing ratio of the sand overlying clay with woven coir geotextiles at the interface decreased after the chemical treatment whereas the trend was reverse in case non-woven geotextiles. The unsoaked bearing ratio of the sand overlying clay with the treated/untreated woven and non-woven coir geotextiles at the interface was higher than the soaked bearing ratio. The C: O ratio both for the woven and the non-woven coir geotextiles increased after the chemical treatment. The emissions of Si increased for the woven coir geotextiles whereas it decreased for the non-woven coir geotextiles after the chemical treatment. The chemical treatment results in the modification of the surface of both the untreated woven and non-woven coir geotextiles.
摘要
本文研究了两种经编织和无纺布处理的椰壳土工布在界面上覆砂粘土的承载比特性. 采用对氨基苯酚、高碘酸钠、氢氧化钠等化学药剂对椰壳土工布进行处理. 结果表明，经过化学处理后，覆土与椰壳机织土工布界面上的砂的无泡/浸水承载比降低，而无纺土工布的无泡/浸水承载比则相反. 经处理/未经处理的椰壳土工织物与未经处理的椰壳土工织物的界面上覆砂的不浸水承载比高于浸水承载比. 化学处理后，椰壳土工织物和无纺土工织物的C:O比均有所提高. 化学处理后，椰壳机织土工布的Si排放量增加，而无纺布的Si排放量减少. 化学处理使未经处理的椰壳土工织物和无纺布的表面都发生了改性.
