摘要
根据部分桩基完整性检测结果,采用因果分析法辨识冲击成孔灌注桩施工中存在的风险,并用改进的AHP得出各因素权重的大小,显示主要因素和次要因素,为冲击钻孔灌注桩施工重点控制提供依据。从实际工程调查以及搜集资料、因果分析建立层次结构模型、最优传递矩阵的构造、评价分析、控制风险等方面对实际工程案列进行分析,得到科学的、有预见性的结论,为冲击钻孔桩施工提供一种逻辑性强、适用性强的分析方法。
According to the test results of pile integrity, causal analysis method was adopted to identify the risks in impact drilling pile construction. And the improved AHP is used to get the weight of each factor and show primary and secondary factors to provide guidance for key risk controls. From the practical engineering investigation and data collection, causal analysis, establish hierarchical structure model, the optimal transfer matrix construction and evaluation analysis and risk control, a practical engineering case is analyzed, scientific, predictable conclusions are gained. A strong logic, strong applicability analysis method for impact bored pile construction is provided.
