Abstract: Based on the relative independence of mathematical cover and physical grid, and considering the action of truely existent various equilibrant force in system for system balance, a method of simulation for excavation unloading using numerical manifold method in geotechnical engineering is proposed. Compared with the traditional numerical method, the numerical manifold method need not calculate the released load on excavation face, need not prepare special element for unloaded material part; simple mathematic grid can meet the arbitrary course of excavation; so it is more convenient and effective; at the same time, high-order manifold method has better precision for excavation.

Key words: numerical manifold method, mathematical cover, geotechnical engineering, excavation
