Roller compacted concrete dam construction progress-cost cooperative control method based on BIM technology

Abstract

Roller compacted concrete dam construction progress-cost cooperative control method based on BIM technology comprises the following steps: establishing a dam simulation three-dimensional entity model;compiling a dam concrete pouring simulation information model; importing three-dimensional entity model and multiple information models of dam simulation into a construction simulation platform, andintegrating the roller compacted concrete dam progress-cost collaborative management information platform through correlation of data information; displaying the implementation conditions of the construction progress plan and the construction cost plan; monitoring an improved value index in the construction process by utilizing a secondarily developed platform plug-in and an improved value methodprinciple, and a project manager adjusting the construction progress-cost planning in time according to early warning information of monitoring deviation to achieve progress-cost correction, so as torealize collaborative management and control of the two, and finally, realizing a predetermined progress-cost target. By means of the method, visual simulation, construction information inquiry and tracking monitoring of the roller compacted concrete dam construction process can be achieved, a basis is provided for decision making and management of a project manager, and the construction progressis improved. And the cost management efficiency and the collaboration are improved.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower construction management and visualization, in particular to a BIM technology-based construction schedule-cost collaborative control method for a roller compacted concrete dam. Background technique [0002] Roller compacted concrete technology has developed rapidly. Because of its advantages such as fast construction speed, less cement consumption, low cost, safe and reliable quality, etc., it is widely used in large-scale water conservancy and hydropower projects, and the number of roller compacted concrete dams in my country is also increasing. . Nevertheless, the construction process of the RCC dam is a very complex system engineering, with high construction intensity, tight construction period, and strict construction process control requirements, which make the management and control of the RCC construction process difficult, and the schedule and cost objectives are mutually excl...
