摘要
为了反映坝基岩体的非线性力学特性,在考虑岩性差别较大的岩层之间设置接触单元的基础上,利用ABAQUS软件模拟了某重力坝在动力工况下的失稳破坏过程,重点探讨了坝体-地基系统的抗滑稳定性问题。结果表明,该大坝的强度储备安全系数为2.8,大坝整体抗滑稳定性可控。
In order to truly reflect the nonlinear mechanical properties of dam foundation rock, some contact elements are considered to be set between different rock stratums. The failure process of a gravity dam under seismic condition is simulated based on ABAQUS, and the anti-sliding stability charaeteristies of dam-foundation system are analyzed in detail. The results show that the strength reserve coefficient of gravity dam is 2.8, so the dam anti-sliding stability is controllable.
