木兰溪下游防洪工程淤泥施工技术研究

福建莆田木兰溪下游防洪工程是在南方滨海淤泥软基地带进行大规模河道裁弯取直的工程，工程地质复杂，技术难度大．基于工程地质的特殊性，在实施大规模河道裁弯取直开挖新河道的过程中，如何利用新挖河道的大量淤泥质土进行筑堤、保护环境、少占耕地、节约投资、实现土方平衡成为工程建设中主要技术问题之一．文中阐述了工程建设中利用淤泥土进行堤防填筑施工的实践，总结了利用河道淤泥质土筑堤的施工经验．

Muddy soil construction technology considerations for the lower Mulan Creek flood control works

The lower Mulan Creek flood control works are situated at south China's coastal region. The works are founded on muddy soft stratum with complex technical geology and difficult conditions for construction. How to utilize the muddy soil excavated for dike fills in the process of constructing the new river bed, and how to protect the environment, occupy fewer farmland, save the capital investment and realize the balance excavations-fills, these have been ones of the most important technical problems for this construction.The construction practice of using muddy soil material to construct a dike structure and its construction experience are summarized in this article.
