Based on the finite element strength reduction method,the typical slopping breakwater structure is simulated,and the influence of factors affecting the stability of the slope embankment on its safety factor is analyzed.Results show that strength parameters and slope ratio are positively correlated with safety factor,while load and slope height are negatively correlated with safety factor.However,there is no clear correlation between water level and safety factor.Some related suggestions are put forward.The selection of foundation treatment schemes for sloping embankment is mainly based on the surrounding engineering cases,experience,cost and construction capacity,etc.It lacks the comprehensive selection of indicators.Aiming at this problem,a fuzzy comprehensive evaluation model of foundation treatment scheme is established by using the method of fuzzy synthesis to synthetically compare and select the scheme index.The model is verified by an actual project,and the results show that the model is practical and effective.
