摘要
顶推施工是一种桥梁施工方法,以某顶推施工为依托工程,对连续刚箱梁顶推施工进行风险评价与分析。使用模糊综合评价法,经过专家调查分析,将整个顶推施工分解为若干个子系统并赋予权重,然后通过层次分析法对各项风险进行判断并构造判断矩阵,最后计算得出目标风险值W=2.82,在2.5(一般风险)和3.5(较高风险)之间,属于较高风险。然后根据计算结果,对分解的若干子系统可能出现的风险进行具体分析,对安全生产有积极的促进意义。
Jacking construction is a bridge construction method.Based on a certain jacking construction project,this paper makes a risk evaluation and Analysis on the jacking construction of continuous rigid box girder.Using the fuzzy comprehensive evaluation method,after expert investigation and analysis,the whole jacking construction is decomposed into several subsystems and given weights,and then the risks are judged by analytic hierarchy process and the judgment matrix is constructed.Finally,the target risk value W=2.82 is calculated,which is between 2.5(general risk)and 3.5(higher risk),belonging to higher risk.Then,according to the calculation results,the possible risks of several decomposed subsystems are analyzed in detail,which is of positive significance to promote safety production.
