深厚软土地基上围垦海堤稳定时效性研究与分析

Study and Analysis on Stability Timeliness of Reclamation Seawall on Deep Soft Soil Foundation

该文针对海堤静力整体稳定性和渗流稳定性,以浙江某软土地基上围垦海堤为研究对象,利用有效应力极限平衡分析法和有限元应力分析法,从数值模拟与分析层面,研究分析不同强度参数取值海堤整体稳定性安全系数和时效稳定性的发展规律,为围垦工程方案设计和危害整治提供科学依据。

In this paper, aiming at the overall stability and seepage stability of seawall statics, the reclamation seawall on a soft soil foundation in Zhejiang Province is taken as the research object. Based on effective stress limit equilibrium analysis method and finite element stress analysis method, the development law of safety factor and stability timeliness of seawall with different strength parameters is studied and analyzed from the level of numerical simulation and analysis levels. It provides scientific basis for the design and harnessing of hazards of reclamation project.
