摘要
运用大型通用有限元软件ANSYS,采用Drucker-Prager弹塑性模型对岩土体进行模拟,建立由某高速公路高架桥钻孔灌注桩、供水隧洞、岩土体构成的三维整体有限元模型。从桩基的承载性状及变形特性分析入手,以模型的沉降场及应力等方面,研究桩基对供水隧洞产生的影响,以及两者之间的相互作用。
The three-dimensional finite element model which is consist of rock and soil composition,water supply tunnel and grouting piles of a highway overtake bridge was established,through the simulating the rock mass with the large-scale finite element software ANSYS,and Drucker-Prager elastoplastic model.This paper introduces the impact of piles on the tunnel and their relationship based on the analysis of pile bearing behavior and deformation characteristics,and the model settlement and stress etc.
