| 摘 要： | 盾构隧道施工会对邻近既有建筑物产生潜在的安全风险。首次将模糊层次分析法引入对邻近盾构隧道的建筑物安全风险评估中。分析建筑物和隧道的影响因素,遴选出主要因素作为模糊层次评估方法的影响因子,建立了邻近盾构隧道的建筑物风险指标体系。采用专家打分法确定层次分析中各风险评价指标的权重,建立邻近盾构隧道的建筑物风险模糊层次评估模型。运用本文方法,对武汉长江盾构隧道上方的武汉理工大学电教楼进行了风险评估,得到的评估结果符合实际工况,验证了本文方法的可靠性。

| Abstract: | Potential security risk may be appeared during shield tunnel construction in adjacent existing buildings. A risk-assessment method was put forward to analyze the influence of shield tunnel construction on nearby existing building. Then, the influencing factors were selected for fuzzy hierarchy evaluation method, and the risk index system was established. Then it determined weighing of each index by using the AHP (analytic hierarchy process). It studied the risk-probability and risk-loss of existing buildings caused by shield tunnel construction through the fuzzy comprehensive evaluation method. A risk-assessment case was studied by using fuzzy-AHP which is electronic teaching construction built in Wuhan University of Technology above the Wuhan Changjiang River Tunnel. The reliability of this method has been proved by the result of this case study. |
