河堤应急消险工程施工期安全状况评价
|
摘要
河堤应急消险工程施工期安全状况的常规评价方法主观性强、综合性弱,因此引入Fuzzy功效系数法对其进行改进。本文以徐州市铜山区段黄河故道干河(丁楼闸—西三环段)工程为例,对该段河堤开展了施工期安全控制设计及实时监测,测量该工程施工期的防洪墙沉降、堤顶道路沉降、临河步道水平位移、防洪墙水平位移等数据,并基于Fuzzy功效系数法对其安全状况进行综合评价。该方法具有较好的推广价值,其分析过程可为施工期安全状况评价工作提供参考与借鉴。
Traditional assessment methods of safety conditions at construction period for emergency relief projects have the disadvantages of significant subjectivity and weak comprehensiveness; therefore, the fuzzy efficacy method is introduced to improve them. A river levee emergency relief project in Xuzhou City is used as a case study. Safety control design and real-time monitoring during construction period are carried out for the embankment. The data on the vertical displacements of anti-flood wall as well as road work at the levee top, and the horizontal displacements of riverine trail as well as anti-flood wall are measured. The safety condition is comprehensively assessed based on the fuzzy efficacy method. The proposed method has a good value of popularization, and the analysis process can provide reference and experience for the assessment work of safety conditions at construction period.
