摘要
Disclosed in the present invention is a talus active earth pressure action point correction method considering a particle size effect. The method comprises: arguing the effectiveness of a PFC2D numerical model first, then finding a boundary relative particle sizes of a simulated talus, then establishing a change trend between the relative particle sizes and the active earth pressures, and finally, obtaining a talus active earth pressure action point correction formula by means of summarization of the change trend, so as to calculate the talus active earth pressure action point. The talus active earth pressure action point correction method resolves the problem of the calculation inaccuracy of the active earth pressure action point because there is no earth pressure theory considering the particle sizes when the active earth pressure is calculated.
