Comprehensive safety control method for long-term environmental safety in waste slag project

The invention discloses a comprehensive safety control method for guaranteeing long-term environmental safety in a waste slag project. The comprehensive safety control method comprises the following steps: controlling the field stability and safety of a waste slag field; controlling the stability and safety of the waste slag slope; and controlling stability and safety of the main body structure. The method has the advantages that the quantitative evaluation of the system is guaranteed, and the fundamental site stability risk of the waste slag site is avoided; test items are reduced, and the problems of sampling representativeness and test representativeness are solved; and the overall stability of the waste slag project is improved through the comprehensive effect of factors that the slope ratio, the statistical characteristic value of the multi-stage limit emission slope angle and the wide step have certain conservative characteristics, the shaping slope ratio is smaller than the slope angle, and the wide st
