摘要

拱坝是一种很重要的坝型，具有体型优美、投资省等优点，但是其对坝肩岩体要求很高，因此，为了了解拱坝-坝肩整体安全性状，采用FLAC大变形软件对拱坝-坝肩稳定性进行了三维研究分析。由于FLAC软件前处理有所欠缺，因此采用AUTOCAD和ANSYS联合进行三维地质可视化建模，AUTOCAD用于基本数据信息的处理，ANSYS对基本数据信息进行再加工得到单元模型，然后把单元模型转入到FLAC做数值计算。通过计算分析，得出了有益的结论。

Abstract

Arch dam is an important type of dams due to its beautiful body and lower cost and so on. But it has a high requirement to the rock mass of dam abutment. The three-dimensional stability analysis of arch dam-dam abutment is done by using FLAC large deformation software in order to know the safe property.The three-dimensional geological visualization model is done by combined using Auto CAD and ANSYS due to the preprocessing shortage of FLAC software.The basic data information is processed by using Auto CAD

the element model is obtained by reprocessing the basic data information by using ANSYS software.The element model is turned into FLAC to do numerical calculation.Some useful conclusions are obtained by numeration analysis.
