库伦土压力理论

俯斜墙背条件下朗肯与库伦土压力理论的研究

Research on rankine 's earth pressure theory and coulomb 's earth pressure theory on overlook wall

目前，对挡土墙的土压力计算仍沿用经典的库伦土压力理论（C.A.Coulomb，1773）和朗金土压力理论（W.J.Rankine，1857）两大理论。

At present , two theories are still used to calculate the soil pressure , which are classic Coulomb soil pressure theory and Rankine soil pressure theory .

以库伦土压力理论和郎肯土压力理论为土压力计算方法的起源，发展至今，土压力的计算方法丰富多彩。

Coulomb earth pressure theory and Rankine earth pressure theory are the origin of earth pressure calculation method , to today , earth pressure calculation method is colorful .

以库伦土压力理论为基础，用3种方法，推导出了倾斜填土面上作用着均布荷载的土压力计算过程。

On the basis of coulomb 's theory of earth pressure , this article , using three methods , deduces earth pressure 's calculation process of uniform load acting on inclining earth-fill .

目前挡土墙土压力的计算一般都采用库伦或朗肯土压力理论，但经典土压力理论建立在一定的假设条件基础上，有时与工程实际情况不符。

The classical Coulomb and Rankine earth pressure theory are widely used in the calculation of retaining wall . However , these theories are based on some hypotheses , and some practical projects can not accord with them .

经典的库伦或郎肯土压力理论是建立在填土为半无限体的假定基础上，因此对于这种填土宽度有限的情形并不合适。

As the classical Coulomb and Rankine earth pressure theory are based on the hypothesis that the filling is a semi-infinite body , it is inappropriate to calculate the earth pressure in this case using the classical pressure theories .
