摘　　要：对边坡花岗岩风化孤石工程危险性预测时尚无规范依据和行之有效的方法。影响边坡花岗岩风化孤石稳定性的因素较多且不确定性较强,引入层次分析法,建立危险性评价层次结构模型,根据工程实践经验和反馈给出影响因素重要程度评判矩阵,从而得到影响因素重要程度权重矩阵,根据各影响因素定性评分得到危险性评价结论,且具有半定性半定量的特点。通过工程对比,有较好的一致性。There is no standard basis and effective method for predicting the engineering risk of weathered granite boulders on slopes.There are many factors and uncertainties that affect the stability of granite weathered boulders on slopes.The introduction of analytical hierarchy process(AHP)and the establishment of a hierarchical model for risk assessment have been applied to derive a matrix of factors that have important importance based on engineering practice and feedback.The weight matrix of factors has been derived.Based on qualitative scores of various factors,a conclusion of risk assessment has been drawn,which is characterized by being both qualitative and quantitative.There is a good consistency through engineering comparison.
