Abstract

The invention relates to a simulation method for a high arch dam construction. The simulation method comprises the steps of: a) collecting data used for reflecting the construction progress status; b) carrying out data reduction and data integration on the collected data; c) obtaining an incidence relation of data in a data warehouse by a Boolean type association rule mining algorithm based on a two-stage frequent itemset theory recurrence method; d) comparing the obtained inter-data incidence relation with data in a pouring decision rule base in a construction simulation system one by one to perfect the pouring decision rule base of a simulation system; and e) according to a construction determination type parameter, selecting a simulation system parameter by the incidence relation. According to the simulation method for a high arch dam construction, which is disclosed by the invention, a construction rule adaptive to the self characteristics of an engineering, a construction simulation parameter and an influence rule on the construction progress by various factors are obtained, the accuracy and the efficiency of the simulation system are obviously improved, and a guide function of the construction simulation system in high arch dam construction progress control is greatly reinforced.

Description

technical field [0001] The invention relates to the simulation design of water conservancy projects through data mining, in particular to the simulation method of high arch dam construction through data mining. Background technique [0002] Using computer simulation technology to analyze the construction progress of high arch dams is an advanced method that has been gradually popularized and used in the field of water conservancy engineering in recent years. The main principle is to generalize and abstract the construction process of the high arch dam, establish a computer simulation model corresponding to the actual construction process, imitate the actual system operation process, and analyze the dynamic change law of the system state over time. [0003] As an important technical support means for construction schedule control and decision-making, construction simulation technology has played an important role in the design scheme demonstration and construction schedule co...
