利用有限元分析离心模型试验的可靠性

Finite Element Analysis of the Reliability of the Centrifuge Model Test

随着我国经济高速发展,机场建设作为一个非常重要组成部分,本文以广西河池机场项目为依托,项目主要研究机场高填方填石路堤自身稳定性控制技术,采用TLJ-150A大型离心机进行离心试验,运用现有离心模型试验的原理和基本理论,分析研究高填方填石路堤的自身沉降规律。本文主要是以ANSYS有限元软件为媒介对现场路堤和离心模型试验路堤模型分别进行有限元计算在重力荷载下的自身沉降,用以验证离心模型试验在填石路堤沉降研究中可行性,为以后在工程实践中的应用提供新的理论依据。

With the rapid economic development, the construction of the airport is as a very important part, the article relies on the Guangxi Hechi Airport project to research the stability control technology of the Airport embankment of rock high-fill, to use the TKJ-150A large centrifuge to make the test that use of the existing centrifuge model test principles and basic theory, analysis the embankment of high-fill settlement law. This article is mainly based on ANSYS finite element software as the media on the scene embankment and centrifuge model test embankment model finite element calculation of sedimentation under gravity load to verify centrifuge model tests to study the feasibility of Stone Embankment settlement, to provide a new theoretical basis in the future engineering practice.
