Abstract
With the different height of the backfilling soil of the counterfort retaining wall in the flood control project in Baihe County down-town as the study subject and by application of Lizheng geotechnical software and ANSYS 3D finite element software, safety factors and stress variation of the counterfort retaining wall at various conditions are calculated.Furthermore, the water level drop range ratio is introduced.sta-bility and action of the counterfort retaining wall in condition of the water level prompt drop are analyzed accordingly.In consideration of im-pacts on the retaining wall by its general stability as action, the control condition of the counterfort retaining wall is judged.The calculation shows that the control condition of the counterfort retaining wall is related to the soil backfilling height.When the height of soil backfilling be-hind the retaining wall is the same as the retaining wall height, its control condition is the one of water level prompt drop.When the cantile-ver at the top of the retaining wall occurs, stability of the retaining wall is better.In condition of high water level before the retaining wall a-vailable, the tensile stress of the wall increases rapidly.The control condition of the retaining wall is the check flood level.Based on this, the control condition of the retaining wall can be determined.关键词
