| The land sites of Shougang Jingtang steel joint company is formed by the sea sand, and the thickness of soil is 0.7m-6m and average thickness reaches 4m.The corrosion and groundwater situation of steel company is complicated.According to the water quality analysis results,the groundwater is moderately corrosive to concrete,and weak corrosive to the steel in the reinforced concrete structure which is under the water for a long time,but strong corrosive in dry-wet alternating conditions.So,conducting the durability design of concrete to Shougang Jingtang steel joint company is necessary.Through the analysis of corrosive environment,the article determines the engineering environment categories,and developing the high-performance concrete durability test,studying the performance of carbonation,freeze-thaw and chloride erosion to concrete material used in engineering.The article discusses the durability design method of concrete structure. Combining with engineering practices,and starting from engineering anticorrosion measures,the durability design plan of this project is put forward.This article analyzes the economic benefit of this project,and ensures the engineering project with good safety,durability and economy. |
