基于熵权法-CIM模型的高速公路施工临近房屋安全风险评价

为了评估高速公路施工对临近房屋的安全影响，基于房屋因素、施工技术与管理因素、房屋周边环境因素，提出了高速公路施工临近房屋安全风险评价指标体系。以某高速公路施工临近10处房屋为研究对象，采用基于熵权法-CIM模型的混合安全风险评价方法，首先计算指标权重；再以其中1处房屋为例，确定其安全风险概率，结果表明:该处房屋安全风险总体较高，基本符合工程施工中的监测结果。

Safety risk assessment on buildings adjacent to construction site of expressway based on entropy-weight method and CIM model

In order to assess the safety impact of expressway construction on the adjacent buildings, an index system of safety risk assessment on buildings adjacent to construction site of expressway was put forward based on the building related factors, the construction technology and management factors, and the building surrounding environment factors. Taking ten buildings adjacent to the construction site of a certain expressway as the research object, the mixed safety risk assessment method based on entropy-weight method and CIM model was applied to calculate the index weight at first, then the safety risk probability of a building among them was determined. The results showed that the safety risk of the building was generally high, which basically accorded with the monitoring results during the engineering construction.
