摘要
利用ABAQUS有限元软件,采用平面应变有限单元法,研究深基坑中双排桩支护结构的位移和弯矩内力等变化。分析双排桩排距、桩距、连梁刚度和被动区土体加固对双排桩支护的影响,结果表明排拒、连梁刚度和加固被动区土体能显著改善双排桩支护效果,而桩距的影响不明显。
With plain strain finite element method,the characteristis of double-row piles of excavation of foundation pit are studied through the FEM sofeware ABAQUS.Based on an actual example,some influencing factors have been analyzed,such as the top-beam stiffness and the distance between rows of piles.The results show that the top-beam stiffness and reinforcing passive zone soil can significantly improve the supporting effect of double-row piles,but the impact of the distance between the piles is not significant.
