氯离子侵蚀作用下扶壁式挡土墙极限承载能力

The ultimate bearing capacity of buttressed retaining wall under the chloride ion erosion

以某变电站工程扶壁式挡土墙设计案例为对象,根据朗肯土压力理论计算挡土墙后土侧压力,研究在设计使用期内的氯离子扩散及钢筋锈蚀过程,并进行了独立断面和整体结构的极限承载能力研究,为其结构设计和优化提供了依据。

Taking the buttressed retaining wall design case of a transformer substation engineering as the object, according to the Rankine soil pressure theory calculation of last earth pressure of retaining wall, researched the chloride ion diffusion and reinforced corrosion process in design trial period, and researched the uhimate bearing capacity of independent section and overall structure, provided basis for structure design and optimization.
