Embodiment

[0036] 1. Identify different types of mechanical accident risk factors based on the super high-rise accident case database:

[0037] As mentioned above, there are many risk factors that affect the safety of construction machinery. Based on the super-high-rise accident case database, through the analysis of the accident case database, it is identified that they include: "unsafe behavior of people", "unsafe state of machinery" and "Unfavorable environment" three categories of systemic risk factors.

[0038] Among them, human risk: mainly refers to the unsafe behavior of people, which is divided into unsafe behaviors such as management personnel, installation and demolition workers, maintenance workers, and special workers;

[0039] Mechanical risk: mainly refers to the unsafe state of tower cranes and construction hoists, divided into unsafe states such as mechanical quality defects, installation defects, and safety device defects;

[0040] Environmental risk: mainly refers to ...

Abstract

The invention discloses a super high-rise construction machinery key safety risk analysis method based on a complex network, and relates to the technical field of application of a complex network theory in building construction. The super high-rise construction machinery key safety risk analysis method based on the complex network is characterized by comprising the following steps: A, identifyingdifferent types of construction machinery accident risk factors according to a super high-rise construction accident case library; b, carding causal relationships between risk events and factors through a fault tree, and establishing an adjacent matrix; c, constructing a directed unauthorized complex network system model by using software UCINET and taking the adjacent matrix as an input parameter, and outputting the centrality of each node; and D, quantitatively evaluating the safety risk criticality of the super high-rise construction machinery according to the node centrality. According tothe method, in the construction process of the super high-rise building engineering, based on control of mechanical risk factors, maintenance and management of mechanical equipment and components areenhanced, potential safety hazards are greatly controlled, and the safety level of the super high-rise building engineering is improved to a great extent.

Description

technical field [0001] The invention relates to the technical field of application of complex network theory in building construction, and specifically refers to a complex network-based key safety risk analysis method for super high-rise construction machinery. Background technique [0002] With the development of my country's social economy, construction technology continues to improve, and the height of buildings continues to increase. Up to now, more than 30 super high-rise buildings above 300m have been completed in China, and nearly 100 super high-rise buildings above 300m are under construction or proposed. The construction industry is a high-risk industry. Due to the special operation method, once a safety accident occurs, especially a major mechanical accident, it may have a huge impact on personnel, machinery, and the economy. Risk is a potential factor that causes accidents. Identifying the root causes of accidents and rectifying potential safety hazards can effec...
