It is the top of the six major construction accidents. Researches about falling accidents stay in the parts of the qualitative analysis about the causes and the preventive measures ，etc. There is no research on the optimal safety investment analysis for such accidents. By trying to build the safety investment model of the optimized allocation on the FTA （Fault Tree Analysis ）method ，this paper analyses the practical engineering cases，and makes a optimized allocation between each specific safety input based on a given total safety investment so that to minimize the probability of the accident. Results show that the model has practical significance on guiding the specific safety investments into all kinds of accidents. The empirical
