Method for simulating influence of sand and gravel dam foundation piping erosion on stress deformation of dam
The invention discloses a method for simulating the influence of sand and gravel dam foundation piping erosion on stress deformation of a dam. By means of the method, the influence of the sand and gravel dam foundation piping erosion on the stress deformation of the dam can be described quantitatively, the influence of the piping erosion on the dam can be analyzed and controlled, and therefore the safe operation of the whole dam is guaranteed. The method comprises the steps that firstly, simulating calculation is conducted on a dam body during dam body filling and water inpouring, and when the seepage slope of sand and gravel in a dam foundation exceeds a critical piping slope, it is judged that piping erosion starts; secondly, piping erosion and dam stress are calculated and coupled, and the result of the influence of piping erosion on the stress deformation of the dam is obtained.
