海滨深厚软基上围垦造地工程固结沉降分析方法研究

Research on consolidation settlement analysis method of deep soft foundation in reclamation projects of coastal region

滨海地区围垦造地工程多涉及深厚软基的处理,其排水固结过程比较复杂,影响因素包括软土的物理力学性质、土层条件、荷载条件、处理方法及工期等。本文依据有限元数值分析理论与方法,以温州市龙湾区海滨围垦造地工程为例,对海滨围垦造地工程施工期的固结沉降进行了计算分析,并预测了工程运行过程中的沉降量,结果表明有限元数值分析方法很好地应用于海滨围垦造地工程固结沉降问题中,为同类型工程固结沉降分析和处理措施提供技术参考。

Deep soft soil foundation always exists in reclamation projects of coastal region. However,thedrainage consolidation process of the kind of foundation is more complicated since the impact factors in-clude the physical and mechanical properties of soft soil, soil conditions, loading conditions, processingmethod and construction period,etc. In this paper,on the basis of theory of finite element numerical meth-od,a reclamation projects of coastal region in Wenzhou Longwan beach is chosen to verify the related ap-plicability. As an example,the consolidation settlement of the projects during construction is calculated andanalyzed. And the long-term settlement deformation is forecast. The research results show that the finite ele-ment numerical method can be well applied to solve the consolidation settlement problem of the reclamationengineering of coastal region and provide technical reference for treatment measures in similar projects.
