| 摘 要： | 在平面应变条件下,应用广义虎克定律结合Lade-Duncan屈服准则,得到了考虑中主应力影响的主动和被动土压力计算公式,其计算出的主动土压力比Rankine主动土压力小,而计算出的被动土压力比Rankine被动土压力大,对实际工程具有一定参考价值。

| Abstract: | Under the condition of plain strain,formulas both of the active and passive earth pressure considered the intermediate principal stress are deduced by the Lade-Duncan yield criterion.From the calculation results,it shows that the active earth pressure is lower than the one calculated by formula of Rankine earth pressure,for the passive earth pressure,on the contrary,the later is lower than the former,which can provide valuable reference for similar projects. |
