摘要:

为精准识别火电建设工程循环水系统沉井施工中下沉位移偏离风险,避免其对后续盾构工程施工安全造成不利影响,本文基于N-K风险耦合模型系统分析沉井下沉偏移的关键影响因素,通过多因素耦合作用机制量化分析,计算各因素的耦合值,确定其影响权重,提出优化施工工序和改进施工工艺等措施,实现沉井偏移的有效纠偏与风险控制。

Abstract:

In order to accurately identify the risk of sinking displacement deviation in the construction of circulating water system sinkhole of thermal power construction project, and to avoid its adverse impact on the construction safety of subsequent shield project, based on the N-K risk coupling model, the key influencing factors of sinkhole sinking deviation were systematically analysed, and the quantitative analysis of multi-factors coupling mechanism was carried out to compute the coupling value of each factor, and then to determine the weight of its influence. Accordingly, it is proposed to achieve effective correction and risk control of sinkhole offset by optimising construction procedures and improving construction technology.
