Foundation pit support risk early warning method, system and equipment in urban rail transit engineering
The invention relates to the technical field of foundation pit supporting risk management and control, in particular to a foundation pit supporting risk early warning method, system and equipment in urban rail transit engineering, and aims to avoid subjectivity of risk judgment. The risk early warning method provided by the invention comprises the steps of determining an early warning level suggested to be released according to an early warning criterion corresponding to a current dangerous state; capturing K monitoring points in an adjacent area of a preset range according to the generation position of the dangerous state; respectively acquiring monitoring data of J adjacent time points for each monitoring point; according to a run test principle, carrying out randomness test on the monitoring data of each monitoring point, and determining whether the monitoring data of each monitoring point has trend change or not; the number ratio of the monitoring points with the monitoring data trend change is calculated, and then the actual danger level is determined; and issuing a final early warning level according to the early warning level suggested to be issued and the actual danger level. According to the invention, the early warning level can be objectively judged.
本发明涉及基坑支护风险管控技术领域，具体涉及一种城市轨道交通工程中基坑支护风险预警方法、系统及设备，旨在避免风险判断的主观性。本发明提出的风险预警方法包括：根据当前危险状态对应的预警准则，确定建议发布的预警等级；根据危险状态产生的位置，在预设范围的邻近区域内捕捉K个监测点；对每个监测点分别采集J个邻近时间点的监测数据；根据游程检验原理分别对每个监测点的监测数据进行随机性检验，确定每个监测点的监测数据是否发生了趋势性变化；计算监测数据发生趋势变化的监测点的数量占比，进而确定实际危险等级；根据建议发布的预警等级以及实际危险等级，发布最终的预警等级。本发明能够客观地判断预警等级。
