Three-dimensional digital model-based hydraulic and hydropower engineering progress monitoring method

Abstract

The invention discloses a three-dimensional digital model-based hydraulic and hydropower engineering progress monitoring method. The method comprises the steps of 1, performing modeling: reading a hydraulic engineering two-dimensional drawing or directly performing hydraulic engineering design, and performing model building by utilizing CATIA three-dimensional design software, wherein a modeling detail requirement is greater than LOD300; 2, performing model division: according to a progress plan, project demands and project characteristics, dividing a design model in the step 1 into progress models, and customizing specific identifiers for names of the progress models, wherein the name of each progress model after division is divided into two parts: the specific identifier and a number; 3, writing the names, as main keys, of all the progress models after division into a database, and then establishing other fields; and 4, performing secondary development on Catia Composer Player. Therefore, the needs of BIM progress input, deviation comparison, lag analysis and virtual construction functions are met.

Description

technical field [0001] The invention relates to a water conservancy and hydropower project progress monitoring method, in particular to a water conservancy and hydropower project progress monitoring method based on a three-dimensional digital model. Background technique [0002] At present, the progress monitoring and management of water conservancy and hydropower projects (roads, tunnels, diversion tunnels, shafts, inclined shafts, dams, sluices, factory buildings, spillways) is still not detailed enough. The situation of lag and delay in construction period, through research and analysis, the current schedule management methods of water conservancy and hydropower projects mainly have the following defects: [0003] First, the project schedule is too rigid and lacks optimization. At present, we mainly use bar chart and network planning technology, combined with Project and P3 project management software to formulate and manage the project schedule. Using this kind of sche...

Problems solved by technology

[0002] At present, the progress monitoring and management of water conservancy and hydropower projects (roads, tunnels, diversion tunnels, shafts, inclined shafts, dams, sluices, factory buildings, spillways) is still not detailed enough. The situation of lag and delay in construction period, through research and analysis, the current schedule management methods of water conservancy and hydropower projects mainly have the following defects:

Using this kind of schedule plan for schedule control is simply superimposing and calculating the construction period based on mechanical efficiency. When design changes or construction conditions change, it is very difficult to optimize and adjust due to the lack of flexibility of the schedule plan, especially when construction resources exist. When there is interference, it is difficult to calculate the construction period, which causes the actual progress to be quite different from the plan, and also means that the progress control is meaningless

[0004] Second, many factors jointly affect the progress of the project, and it is difficult to comprehensively manage the progress

The comprehensive influence of various factors directly leads to poor progress control in advance, insufficient construction period reserves, inability to manage everything, and delayed construction period

[0005] Third, there are many project participants, and the on-site coordination workload is heavy

Insufficient integration and poor coordination directly lead to delays in the construction period

For example, due to poor cooperation among subcontractors with linking processes, some processes cannot be carried out in a timely manner; unreasonable division of construction sections, poor flow construction organization, etc.

[0006] Fourth, the three major management objectives of progress, quality and cost are mutually restrictive and difficult to balance

In today's schedule management, due to the lack of advanced technology and theoretical support, it is difficult to optimize and balance the three major goals
