Building overall construction scheme determination method based on limiting conditions and weight analysis

Abstract

The invention discloses a building overall construction scheme determination method based on limiting conditions and weight analysis, which comprises the following steps of: splitting the whole building construction scheme, researching each independent sub-project, and combining construction modes after each independent or combined optimal construction mode is obtained, and obtaining an optimal construction scheme of the whole building. According to the method, weight setting is carried out on limiting conditions by calculating influence quantity values of all the limiting conditions, then all construction modes suitable for a subentry project are determined according to the limiting conditions, weight values of all the construction modes are calculated according to coincidence values of all the construction modes in the aspect of different limiting conditions, and the weight values of all the construction modes are calculated according to the coincidence values of all the construction modes in the aspect of different limiting conditions. The construction mode or the combined construction mode with the maximum weight value serves as the optimal construction mode.

Description

technical field [0001] The invention belongs to the technical field of construction schemes, and in particular relates to a method for determining an overall construction scheme of a building based on restriction conditions and weight analysis. Background technique [0002] In order to adapt to the development of the building's underground space structure, super high-rise structure and users' demand for building space, researchers have put forward more and more creations and improvements in the design and construction methods of building structures. For example, for the treatment of building foundations, there are currently deep dynamic compaction methods in holes, cushion replacement methods, dynamic compaction methods, sand and gravel pile methods, vibratory impact methods, cement-soil mixing methods, high-pressure jet grouting methods, preloading methods, Rammed cement-soil pile method, cement fly ash gravel pile method, lime pile method, lime-soil compaction pile method,...

Problems solved by technology

[0003] However, at present, the selection of construction methods basically depends on the subjective judgment of designers and plan decision makers.

This subjective judgment method cannot take into account the safety performance, construction period, and economic cost of the construction method, and it is impossible to compare various alternative construction methods and their multi-directional impacts.

This subjective judgment method has strong subjectivity, and cannot solve the construction method decision-making problem systematically and scientifically.

Through the existing subjective selection of construction methods, it often leads to some force majeure factors in the construction process that have to change the previous selection, which will not only affect the construction quality and construction period to a greater or lesser extent, but also lead to subsequent The chained re-selection of construction schemes greatly affects the construction quality, economic cost and construction period
