Abstract

The invention relates to a hydraulic engineering computer simulation technology and discloses a method for simulating the interference between the hoisting of a steel lining of a cable crane and the concrete pouring in the concrete construction process of a high arch dam. According to the method, the interference between the hoisting of the steel lining and the concrete pouring is abstracted into digital parameters which comprise machine hours of occupying the cable crane in the hoisting process, hoisting intervals, cable crane machine-position interference factors, intermission of mounting the steel lining on the bin surface and the like, and a digital model of the interference between the hoisting of the steel lining and the concrete pouring is established by the digital parameters, and thus, the interference phenomenon between the hoisting of the steel lining and the concrete pouring in a real construction system can be reflected by changing the values of the parameters and carrying out multi-scheme simulation and sensitivity analysis, so that the construction process of the steel lining is more accurately analyzed and forecast. The method is suitable for the building construction of the high arch dam.

Description

technical field [0001] The invention relates to a computer simulation technology for hydraulic engineering, in particular to a method for simulating interference between a cable machine hoisting a steel lining and pouring concrete in the concrete construction of a high arch dam. Background technique [0002] All high arch dams have the characteristics of long construction period and high flood discharge power; the dam body is equipped with complex hole structures such as diversion holes, deep flood discharge holes, flood discharge surface holes, and corridors in the dam. There are construction disturbances such as shared lifting equipment, conflicting space positions, and occupation of working surfaces. Therefore, how to analyze the impact of metal structure construction such as steel lining installation on the progress of concrete pouring is related to The formulation of dam construction progress goals and related decisions. [0003] The existing analysis methods include j...

AI Technical Summary

Problems solved by technology

[0006] The existing computer simulation algorithm only uses the intermission period of steel lining installation to reflect the impact of steel lining installation on concrete pouring, and has the following defects: 1. The number and time factors of steel lining installation on the cable cranes are not considered; machine, and other warehouses may not be able to open the warehouse because there is no free cable machine or the idle cable machine cannot meet the pouring requirements, thus affecting the pouring progress; 2. When the cable machine is working, the adjacent cable The hoisting of the lining may cause space restrictions on the pouring of the adjacent warehouse surface and affect the opening of the adjacent warehouse surface

The existing algorithm does not take into account the spatial restrictions on the concrete pouring of the adjacent warehouse surface by using the cable crane when the steel lining is hoisted

3. The machine hours and number of cable cranes occupied by hoisting steel lining are related to the organization ability, coordination level, construction technology and external environment of the corresponding construction unit. It is difficult for existing algorithms to simulate the construction interference of steel lining hoisting and concrete pouring under different construction parameters.
