一、形成粘性土土压力的破裂面形状 1773年法国工程师C.A.库仑(Culomb)创立的土压力理论,是假定填土没有粘性,土体破裂面(或者滑动面)为平面。1857年英国学者W.J.M.朗肯(Rankine)提出的土压力理论,虽可在计算公式中考虑土的粘结力对土压力值的影响,但他所假定的土体破裂面也仍为平面。然而,大量原型观测资料和实验结果都证明,粘性土在形成土
First, the formation of a clay soil pressure rupture surface shape The French earth pressure theory created by the French engineer C.A. Coulomb (Culomb) in 1773, assumes that the filling is not sticky, the soil rupture surface (or sliding surface) is a plane. The earth pressure theory proposed by the British scholar W.J.M. Rankine in 1857, although the influence of the soil’s cohesion on the earth pressure value can be considered in the calculation formula, the assumed soil failure surface is still flat. However, a large number of prototype observations and experimental results have proved that clay soil is forming soil.
