【 摘 要 】

Blasting squeezing silt technology plays an important role in the marine reclamation and tidal power station seawall project construction. The thickness of soft clay gradually deepening with the ocean engineering progresses to offshore and underwater shoals. The suspended seawall structure appears in over 12m deep soft clay. Carrying out stability analysis of these seawall structures has important significance and application value. In this paper, aim at a revetment engineering stability analysis, the traditional stability analysis method and numerical simulation method were applied. Furthermore, applicability and rationality were analyzed for these methods. Studies have shown that, the safety coefficient obtained by the Swedish strip method is low, and it cannot even meet the requirements of the overall anti sliding stability in the construction period and the earthquake condition. The assumptions of Bishop, Janbu and FLAC based finite element method were closer to the actual engineering conditions. The calculated results were reliable and could be applied to the calculation of the suspended seawall.
