The applicability of calculation method is researched to solve the problem of stability of blasting compaction embankment in soft foundation.Based on calculation formulas of Fellenius circular sliding method and simplified Bishop method and basic principle for searching the most dangerous sliding surface,the two calculation methods are applied to calculate stability of blasting compaction embankment.The most dangerous sliding surface form and pressure condition of soil strip are comparatively analyzed by the two calculation methods.The results show that when blasting compaction embankment is built in soft foundation,stability coefficient obtained by Fellenius circular sliding method is smaller and of larger error.But stability coefficient obtained by simplified Bishop method is closer to the actual condition.Therefore,simplified Bishop method is a better method to calculate stability of blasting compaction embankment in soft foundation.It provides an important reference for blasting compaction embankment design in soft foundation.
