摘要
岩石地基上的扩展基础因其施工简易、造价经济,在工程中得到广泛应用。但由于不同的基岩其岩石刚度也不相同,岩石刚度作为影响基底受力性能的一个重要因素,不同刚度基岩上的扩展基础的基底受力性能也有所不同。该文运用ABAQUS有限元法对不同刚度的岩基上扩展基础基底受力特性进行了数值模拟分析,总结基底反力分布规律,对岩石地基上扩展基础的设计和研究具有参考意义。
The base expansion on rock foundations is massively applied for convenient construction and low cost. However, since different rock foundations have different stiffness, which, as an important influential factor in base stress performance, exerts different stress performances on the base expansion. This paper adopts ABAQUS finite element method to perform numerical simulation analyses on the base stress properties of the base expanded on rock foundations of different stiffness and summarizes the base＇s counter-force distribution rule. It can offer some references for the design and research of base expansion on rock foundations.
