Sustainable usage of dredged clay materials as land reclamation fills

在疏浚工程中，每年有数百万立方米的疏浚材料从河床和海床上被清除。将大量疏浚的废物倾倒入海是很常见的，这会导致严重的环境问题，如水质恶化、破坏水生栖息地、破坏生态系统和在海水中分散细小的粘土颗粒。建议使用疏浚粘土作为填海填料，可大幅减少甚至消除把疏浚粘土倾倒在离岸倾倒地点的需要。如果充分了解稳定疏浚粘土的岩土特性，其潜力是巨大的。

Millions of cubic metres of dredged materials are removed from river and sea beds every year in dredging projects. It is common to dump a significant portion of the dredged spoils into the sea which can result in serious environmental problems such as deterioration of water quality, damage to aquatic habitats, disruption of ecosystems and dispersion of fine clay particles in seawater. The proposed use of dredged clays as land reclamation fill will lead to a substantial reduction in or even eliminate the need for dumping dredged clays into offshore dumping locations. The stabilized dredged clays have great potential if their geotechnical characteristics are adequately understood.
