This invention discloses an intelligent generation method and system for foundation pit construction schemes based on working condition constraint deduction. Through foundation pit engineering data acquisition and analysis, construction of a foundation pit engineering semantic object model, construction of an engineering constraint graph, retrieval and adaptation verification of foundation construction scheme templates, deduction of construction working condition chains, parameter collaborative optimization and generation of candidate foundation pit construction schemes, generation of complete sets of construction schemes, consistency verification, and final scheme output, the invention achieves intelligent and rapid generation of foundation pit construction schemes, improves the accuracy of scheme adaptation to actual foundation pit working conditions, reduces labor costs, and ensures foundation pit construction safety and engineering quality. It solves the problems of low efficiency, insufficient personalization, low matching degree with actual working conditions, and excessive reliance on human experience in existing foundation pit construction scheme generation technologies.

The application relates to the technical field of big data processing and data quality control, in particular to a data cleaning system based on big data, which comprises a data preprocessing center used for collecting multi-source heterogeneous data, generating dimensionless statistical distribution values, and constructing a weighted directed graph; a state mapping unit used for generating a state space vector; an energy verification unit used for comparing a global consistent energy with a preset safety threshold; if the global consistent energy is greater than the preset safety threshold, a logic conflict signal is generated; if the global consistent energy is less than or equal to the preset safety threshold, a logic consistency signal is generated; a gradient repair unit used for generating a dimensionless repair value; and a feedback control unit used for generating a final cleaning result; the multi-source heterogeneous data is set as the final cleaning result; the application solves the problem that the prior art lacks an automatic correction means for system constraints, and improves the convergence speed and precision of repair.
