基于强度折减法的隧道弃渣场稳定性分析
|
摘要
针对成贵高铁高山田隧道出口1号弃渣场,运用FLAC3D强度折减法及运用理正软件对其稳定性进行了分析。结果表明:采用强度折减法比用理正软件分析弃渣场稳定性更合理、全面;该弃渣场短期、长期稳定性均满足要求;挡墙可以确保弃渣场的长期稳定性。
Depending on the engineering of No.1 abandoned dreg site at the exit of Gaoshantian Tunnel on Chengdu—Guiyang high-speed railway,the stability thereof was analyzed by FLAC3 D strength reduction method together with Lizheng software.The result shows that,as regards the analysis on stability of abandoned dreg site,strength reduction method is more reasonable and comprehensive than Lizheng software;the shortand long-term stability of the abandoned dreg are satisfied,and the retaining wall may ensure the long-term stability of the abandoned dreg site.
