The traditional stability evaluation method of corrugated steel web box girder ignores the calculation of evaluation index weight, which leads to large deviation of evaluation results. Therefore, a new fuzzy comprehensive evaluation method for the overall stability of box girder with corrugated steel webs is proposed. According to the structural characteristics of corrugated steel web box girder, the stability coefficient of corrugated steel web box girder is calculated, and the stability calculation index of corrugated steel web box girder is obtained. In this paper, the constraint equation of bridge instability process is introduced, and Midas civil software is used to simulate the instability of box girder with corrugated steel webs during bridge construction. Based on this, the instability of the bridge is analyzed, the index weight of the anti-instability ability of the box girder with corrugated steel webs under different loads is calculated, and the overall stability of the box girder with corrugated steel webs is evaluated by fuzzy comprehensive evaluation. The test results show that this method can accurately evaluate the overall stability of box girder with corrugated steel webs, and the calculation accuracy is increased by 32.7% and the calculation speed is increased by about 1.62 seconds. It has high credibility and authenticity.

Infrastructure construction plays an important role in socio-economic development and urbanization level promotion. For the development of suburban infrastructure in Shanghai, the paper establishes the system of evaluation index and introduces the fuzzy comprehensive evaluation method. To make up for the insufficient of identification ability for determining the index weight by the AHP, the article uses the entropy method to make the results objective, scientific and reasonable.

An indicator system is established for the suitability of projects linked to the increase/decrease in urban and rural construction land based on the field surveys for the old areas to be dismantled in three administrative villages such as Niulandian Village, Tianjiagou Village and Nanchongsi Village of Tianchi Town in Lezhi County of Sichuan Province, and the fuzzy comprehensive evaluation method is used to evaluate indicators. The analysis of evaluation results provides reference for the efficient implementation of projects linked to the increase/decrease in urban and rural construction land.
