Evaluation Method and Application of Seismic Stability of High Cutting Slope During Construction Period
In addition to meeting the engineering stability requirements after the completion of support measures,the cutting slope also needs to be free from large instability deformation and failure during the construction process.In order to comprehensively evaluate the stability of high cutting slope during construction,a comprehensive evaluation method of seismic stability is proposed in this paper.The dynamic stability,plastic deformation and frame beam damage of the slope during the whole construction process are analyzed respectively,and the actual construction sequence and recommended construction sequence of typical slope cases are calculated.The results show that the construction method of"one slope to the bottom"is more susceptible to earthquake in high intensity areas,and the possibility of large sliding increases significantly.However,the method of"one stage excavation and one stage reinforcement"has a lower probability of sliding,and the integrity of the frame beam is better preserved.This method can provide important guiding significance for the seismic stability evaluation of high cutting slope during the construction period.
