A building construction site safety evaluation method based on AHP

Abstract

The invention provides a building construction site safety evaluation method based on an AHP. The building construction site safety evaluation method comprises the following steps: 1) constructing a building construction site safety evaluation index system X; 2) establishing a hierarchical structure; 3) constructing a judgment matrix and calculating a weight value; 4) consistency inspection; and 5) carrying out hierarchical total sorting, wherein the weight of each index in the building construction site safety evaluation index system relative to the total target can be obtained through the steps. According to the method, the influence degree of each risk factor on construction safety is obtained by calculating the weight of each index, then a safety evaluation system of a building construction site safety evaluation model is constructed by adopting a fuzzy comprehensive evaluation method, and corresponding safety countermeasures are provided. The result obtained through the method canobjectively reflect the safety production condition of the building construction unit, and safety management of the building construction site is effectively promoted.

Description

technical field [0001] The invention belongs to the field of building safety construction, and in particular relates to a method for evaluating safety production at a building construction site. Background technique [0002] The rapid economic growth has greatly accelerated the progress of urbanization in my country, and the construction industry, as one of the pillars of the national economy, has developed rapidly. But at the same time, because the construction industry has the characteristics of long construction period, various procedures and intensive operations, the safety accidents in the construction industry are frequent, which is only slightly lower than that in the mining industry among all industries, causing great harm to people's lives and property. [0003] Even though the country has paid special attention to production safety in recent years and has promulgated hundreds of production safety laws and regulations, the effect is still not satisfactory.

Problems solved by technology

But at the same time, due to the characteristics of the construction industry, such as long construction period, various procedures and intensive operations, the frequent occurrence of safety accidents in the construction industry is only slightly lower than that in the mining industry among all industries, causing great harm to people's lives and properties.

[0003] Even though the country has paid special attention to production safety in recent years and has promulgated hundreds of production safety laws and regulations, the effect is still not satisfactory. Compared with developed countries, there are still many accidents and casualties in the tens of billions of output value. big gap

The reason is that the construction safety management level of construction projects in our country is relatively low.
