摘　　要：为了评价高层建筑施工过程中的安全情况,提出了一种基于改进风险度模型的风险评价方法.首先,选择16种常见的安全事故类型构建评价的指标体系.其次,针对传统风险度模型的不足,在"概率"和"影响"的基础上,增加"不可预测性"这一风险属性,并结合三角模糊数,提出了一种基于改进风险度模型的高层建筑施工安全风险评价方法.最后,通过实例验证了方法的可行性和有效性.For the evaluation of high-rise building construction safety risk, a new risk evaluation method based on the improved risk degree model was proposed. Firstly, 16 types of common security incidents were chosen to build the evaluation index system. Secondly, aiming at the shortcomings of the traditional risk model, on the basis of ＂probability＂ and ＂influence＂, ＂unpredictability＂ which is one of the risk attributes was increased, combined with triangular fuzzy number, traditional model of risk degree was improved, a method of safety risk evaluation of high-rise building construction based on the improved risk degree model was proposed. Finally, an example was used to verify the feasibility and effectiveness of the method.
