Deep foundation pit construction safety risk monitoring method, device, equipment and medium
The invention relates to a deep foundation pit construction safety risk monitoring method, device and equipment and a medium. The method comprises the steps of collecting the actual strain value of apile body of a target deep foundation pit; obtaining an optimal soil layer parameter value of the target deep foundation pit according to the actual strain value of the pile body and a preset equivalent underground diaphragm wall model; and taking the equivalent underground diaphragm wall model after the optimal soil layer parameter value is obtained as an equivalent underground diaphragm wall correction model, simulating foundation pit excavation construction, obtaining a foundation pit monitoring parameter change value, comparing the foundation pit monitoring parameter change value with a preset alarm threshold, and visualizing a comparison result in a preset target deep foundation pit BIM model, therefore, monitoring the construction safety risk of the deep foundation pit. According tothe method, the deep foundation pit structure change condition in the deep foundation pit construction process can be effectively monitored, and the deep foundation pit risk management capacity is improved.
本发明涉及一种深基坑施工安全风险监测方法、装置、设备及介质，其方法包括采集目标深基坑的桩身实际应变值；根据桩身实际应变值和预设的等效地下连续墙模型，获取目标深基坑的最优土层参数值；将获取最优土层参数值后的等效地下连续墙模型作为等效地下连续墙修正模型，模拟基坑开挖施工，获取基坑监测参数变化值，并将基坑监测参数变化值与预设报警阈值进行比较，并将比较结果在预设的目标深基坑BIM模型中可视化，以便对深基坑施工安全风险监测。本发明能够有效监测深基坑施工过程中深基坑结构变化情况，提高深基坑风险管理能力。
