摘要

考虑条形荷载对滑裂面倾角的影响，改进了库仑土压力理论的极限平衡方法，对条形荷载下的主动土压力进行研究，得到了条形荷载全部作用于土楔体上和被滑裂面截断两种情况下的土压力理论公式。当荷载为0时，该公式可退化到库仑理论。分析表明，在条形荷载被滑裂面截断时，主动滑裂面的倾角不仅与土体内摩擦角、墙土摩擦角、地面倾角等因素有关，而且还与条形荷载的大小和荷载离开墙背的距离有关，土压力系数K随荷载离墙顶水平距离的增大而减小，随荷载的增大而增大。

Abstract

The effect of strip surcharge on the inclination of sliding plane of soils behind retaining wall is taken into account. New formulas of active earth pressure due to strip surcharge are presented based on Coulomb’s theory. When the surcharge is zero

the formulae are the same as Coulomb’s theory. If the strip surcharge is cut by the sliding plane of soils

it is shown that the obliquity of sliding plane of soils behind the wall is not only related to the angle of internal friction of soil

the angle of wall friction and the inclination of ground

but also to the magnitude of surcharge and the distance of the surcharge from the wall. It is also shown that the farther the surcharge from the wall

the smaller the coefficient of active earth pressure. The bigger the magnitude of strip surcharge

the bigger the coefficient of active earth pressure.
