深厚淤泥爆炸挤淤填石围堤稳定性的有限元分析

Stability of dike constructed by explosive squeezing mud and stone-filling method in deep soft ground based on finite element analysis

结合福建罗源湾可门作业区4#,5#泊位深厚淤泥爆炸挤淤围堤工程,运用Midas/GTS有限元程序建立深厚淤泥爆炸挤淤填石围堤的稳定分析模型。基于有限元强度折减理论,对其安全系数进行求解,探讨相关参数对填石围堤滑动稳定性的影响。

Based on the dike constructed by explosive squeezing mud and stone-filling method in deep soft ground of No.4 No.5 berth at Kemen port,Luoyuan bay,Fujian province,this paper establishes the stability analysis model of dike by Midas/GTS finite element program.The safety factors of stability are solved based on the strength reduction theory,and the effects on stability of relevant parameters of filling stone are discussed.
