摘  要： 目前高层建筑坍塌墙体修复施工质量检测方法无法直观显示出修复区域数值，因此提出BIM模型监管下高层建筑坍塌墙体修复施工质量检测方法。根据BIM模型特性，利用激光扫描技术获取修复区域数据，利用std2计算数值矩阵标准差，剔除其中的影响参数，得到包含修复区域在内的整体坍塌墙体模型，完整地对修复施工中混凝土强度与承台修复两部分进行质量检测。设计仿真实验，将其与动态参数指标方法、有限元模型检测方法所检测到的施工质量检测效果相对比，证明了其能够更好地完成质量检测工作。

Abstract： As the construction quality detection method of high?rise building collapse wall repair cannot intuitively show the value of repair area， a construction quality detection method of high?rise building collapse wall repair under the supervision of BIM model is proposed. According to the features of BIM model， the data of repair area are obtained by means of the laser scanning technology， the standard deviation of numerical matrix is calculated by std2， from which the influence parameters are eliminated， so that the whole collapse wall model including repair area is obtained. The quality detection of the concrete strength and cushion cap repair in the repair construction process are accomplished. The designed simulation experiment show that， in comparison with the dynamic parameter index method and the finite element model detection method， the construction quality detection effect of the designed method is better， which proves that it can better complete the quality detection work.

高层建筑安全风险较大，对施工与建筑维护管理要求较高。我国受到地形影响，较大部分地区处于板块断裂带，容易受到地震影响，造成高层建筑破坏。高层建筑遭到破坏后主要表现为墙体坍塌[1]。高层建筑坍塌墙体修复工作存在较大的危险性，且施工修复质量得不到保障[2]。目前，现有高层建筑坍塌墙体修复施工质量检测方法的准确性有一定提升，但实际应用效果较差，运行费用较高，很难得到推广使用。针对目前现有检测方法存在的问题，提出BIM模型监管下高层建筑坍塌墙体修复施工质量检测方法[3?4]。通过分析坍塌墙体修复工程质量因素，完成质量检测量化，提高整体修复工程质量检测性能。
