摘要
城镇排水箱涵年久失修,受箱涵上覆条件限制,箱涵修复多采用原位修复方式。导流时机选择是涉及箱涵原位修复施工安全的关键问题。考虑施工工艺和工期、导流方式和施工时段等风险因素,建立了导流过程风险测度模型;分析导流风险因素不确定性,比较施工时段和风险变化过程,建立箱涵原位修复施工导流风险分析模型,为城镇箱涵修复时机选择提供参考。
Urban drainage culverts,suffering from years of disrepair and constrained by the conditions above them,are often repaired using in situ methods.The selection of the timing for diversion is a key issue concerning the safety of in situ culvert repair construction.This paper considers risk factors such as construction technology and duration,diversion methods,and construction periods,and establishes a risk measurement model for the diversion process.By analyzing the uncertainty of diversion risk factors and comparing the construction periods with the risk change process,a risk analysis model for diversion during in situ culvert repair construction is established,providing a reference for the timing of urban culvert repairs.
