Specifically, when no settlement displacement is generated in the monitoring and identification, environmental data of one week is collected, normalization processing is carried out on the environmental data, the normalized environmental information is taken as input, and the current measured settlement displacement amount is output as a training model, namely:
wherein ,for the environmental compensation model->For temperature, < >>Is air pressure and is->Is the sedimentation displacement.
S403, carrying out normalization processing on the real-time environment information in the environment information, and inputting the real-time environment information and the sedimentation displacement after normalization processing into an environment compensation model to obtain the sedimentation displacement after compensation.
