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物从河流和海底被清除。将大量疏浚后的渣滓倾倒入海的情况很常见，这会造成严重的环境问题，例如水质恶化、破坏水生生境、破坏生态系统和在海水中散布细小的粘土颗粒。建议使用疏浚粘土作为填海填土，可大幅减少甚至消除向近海倾卸地点倾倒疏浚粘土的需要。如果充分了解稳定疏浚粘土的岩土力学特性，其潜力巨大。

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.
