考虑动水压力影响的土质堤坡稳定性及加固效果评价研究OA

The rapid fluctuation of water levels generates dynamic water pressure within the soil embankment of the river chan-nel,significantly increasing the sliding force on the embankment slope and adversely affecting its stability.Therefore,dynamic water pressure has become one of the factors that cannot be ignored in the evaluation of embankment slope stability.In order to achieve a more accurate evaluation of the stability and reinforcement effect of levee slope,the traditional Swedish strip method is improved by considering the reaction force of anti-slide pile on rock and soil mass of levee slope and the dynamic water pressure caused by water level fluctuation.At the same time,the method is applied to evaluate the stability of the left bank em-bankment slope project of Haohe river in Huaihe river basin and the effect of anti-slide pile strengthening.Through numerical calculation,the stability changes of the embankment slope along the detected potential slip surface before and after the anti-slide pile reinforcement,and the stability degree of the most dangerous slip surface after the anti-slide pile reinforcement are deeply analyzed.The results showed that the safety factor of the original potential slip surface was significantly increased from 1.216 to 1.633 after the reinforcement of anti-slide pile,which fully proved that anti-slide pile plays an important role in im-proving the stability of embankment slope.This method has important practical application value in the stability evaluation of soil embankment slope.
