| With the rapid development of highway construction of our country, there are more and more high slope problems and potential security risks in the construction and operation of the highway,so we need to do some necessary research, analysis and evaluation of the high slope stability problems in the construction and operation of highway through advanced theory and numerical calculation method. Thus, we can provide some corresponding proposals to the design and construction of engineering. So the research and evaluation of the stability of the high slope problems in the construction of Zhuji - Yongjia Expressway.In this paper, I explore and identify the complex rock mechanics parameters, and modeling the slope in FLAC software. Under steady load of bridge foundation, I analyse the stability of the high slope on the bridge side in Section III of Zhu Ji -Yong Jia Expressway. According to modeling under 4 working conditions, such as before and after highway slope excavation, after bridge foundation construction, and after consolidation like anchor construction, I obtain the changes of the movement and the field stress and the stability factor with the cross section K170+014 and K168+490.So we can compare and evaluation of the slope stability, and make the design of the slope protection and bridge foundation more optimize.In this paper, I also analyse the stability of the slope in ANSYS software,comparing in FLAC, make sure that the results is more reliable. |
