摘要
针对地铁施工中存在的高风险,采用模糊数学方法,根据工程地质条件和临近构筑物情况,给出高概率风险事故及相应的风险组成因素,进行实时的风险评价,以减少风险发生的可能性,为施工风险进行有效控制提供便利。基于青岛地铁R3线的工程地质条件及施工环境因素,采用模糊数学进行了R3线施工风险、既有构筑物对R3线施工影响风险和其他重大影响风险源风险评价,得到了R3线施工过程中的风险级别,为设计与施工提供了可靠建议。
In view of the high risk existing in the subway construction,using fuzzy mathematics method,according to the engineering geological conditions and the adjacent structures,given the high probability of accident and the corresponding risk factors,operating the real-time risk assessment,reducing the possibility of occurrence of a risk,to facilitate the construction risk under effective control.Based on the engineering geological conditions and the construction of the Qingdao metro line R3 environmental factors,the fuzzy mathematics method is used for R3 line construction risk,both structures influence on R3 construction risks and other significant risk source of risk evaluation.The R3 line level of risk in the process of construction is got,which provides the reliable suggestions for design and construction.
