Deep foundation pit construction safety risk assessment method and system
The invention discloses a deep foundation pit construction safety risk assessment method, which comprises the steps of constructing a foundation pit numerical model according to foundation pit parameters; predicting a secondary risk attribute index value of the foundation pit at the moment t by adopting the foundation pit numerical model; in response to the fact that the difference between the predicted t-moment secondary risk attribute index value and the t-moment secondary risk attribute index value monitored on site is within a preset range, predicting a secondary risk attribute index valueof the foundation pit at the moment t+1 by adopting the foundation pit numerical model, wherein the secondary risk attribute index value comprises a quantitative risk attribute index value and a qualitative risk attribute index value; calculating foundation pit risk values at the moment t and the moment t+1 by using an evidence reasoning algorithm; and generating a risk assessment report of the foundation pit at the moment t according to the foundation pit risk values at the moments t and t + 1. The invention further discloses a corresponding system. The quantitative risk attribute index value and the qualitative risk attribute index value are fully utilized to perform foundation pit risk assessment, the technical specification is met, and the accuracy is higher.
本发明公开了一种深基坑施工安全风险评估方法，包括根据基坑参数，构建基坑数值模型；采用基坑数值模型预测基坑在t时刻的二级风险属性指标值；响应于预测的t时刻二级风险属性指标值与现场监测的t时刻二级风险属性指标值差别在预设范围内，采用基坑数值模型预测基坑在t+1时刻的二级风险属性指标值；其中，二级风险属性指标值包括定量风险属性指标值和定性风险属性指标值；运用证据推理算法计算t时刻和t+1时刻的基坑风险值；根据t时刻和t+1时刻的基坑风险值，生成基坑在t时刻的风险评估报告。同时公开了相应的系统。本发明充分利用定量风险属性指标值和定性风险属性指标值进行基坑风险评估，符合技术规范，准确度更高。
