锚定板挡土结构的实测土压力及其分析研究

Neasurement and Analysis of Earth Pressure in Anchor Slab Retaining Structures

本文通过对几处锚定板挡土结构工程的多年现场实测及分析研究，得到了土压力大于库仑主动土压力值的结论，提出了锚定板挡土结构墙面土压力的建议计算式和土压力沿墙高的分布图式，并在土压力计算中引入了增大系数概念。

Field measurements and analysis of earth pressure on anchor slab retaining structures weremade for a number of years.It was concluded that the earth pressure is greater than the value fromCoulomb’s equation,Proposed equation of earth pressure in anchor slab retaining structure and earthpressure distribution along the height of the wall are presented.Concept of the enlarged factor is intro-duced in the equation of earth pressure.
