A method and system for safety monitoring of building settlement around foundation pit

Abstract

The application discloses a kind of for foundation pit peripheral building settlement safety monitoring method and system, it is related to safety monitoring technical field, the method includes the following steps: presetting foundation pit peripheral building monitoring index, data is collected and summarized as settlement monitoring history record;Arbitrarily select a historical record and its monitoring index, extract its time window in corresponding time series change curve, pre-process to obtain trend form vector and construct monitoring characteristic trend set;Presetting template library, calculate similarity, reach standard and determine that both match;Collect each working condition normal record to form characteristic sample set, calculate the variation coefficient and weight of single point and space-time correlation characteristics and normalize;Calculate deviation degree and comprehensive health index for the record to be evaluated, determine early warning threshold, real-time identification working condition, calculate real-time health index, according to early warning grade threshold interval executes early warning operation, the application realizes the safety monitoring of foundation pit peripheral building settlement.
