A simulation analysis method for stability of dam foundation surface under osmotic pressure

Abstract

The present application relates to dam foundation data analysis technical field, specifically to a kind of dam foundation surface stability simulation analysis method under the action of seepage pressure, first to the upstream and downstream temperature signal in each period of time Continuous wavelet transform, temperature sequence is decomposed into discrete event with time sequence, energy and waveform characteristics, composite cost function including waveform distortion index and energy-time attenuation is constructed, the preferred input-output event pair corresponding to the most credible advantage transport path in physics is dynamically identified by combining optimization algorithm Then, combined with the transport duration of the through melting channel that has greater influence on stability is short, energy retention rate is high, and signal waveform fidelity is high characteristics, the preferred input-output event is analyzed, so that the stability determination coefficient obtained by the dam foundation surface stability characterized is more accurate, improve the accuracy of dam foundation surface stability analysis according to stability determination coefficient.
