摘要
在土力学中计算土体极限荷载的公式有很多,最常用的公式有太沙基(K.Terzaghi)公式、斯凯普敦(Skempton)公式、汉森(Hansen J.B)公式,各公式适用于不同的前提条件,目前尚无适用于各类土体情况不同荷载作用的统一公式。因土体自身因素、水文环境、外界荷载及错综复杂的各种因素影响,精确计算土体受力极其困难。针对土体液化状态下使用前述三公式计算极限荷载值的情况进行分析,得出在土体液化时计算极限荷载的统一性的结论。
There are many formulas for calculating the ultimate load of soil in soil mechanics.The most commonly used formulas are K.Terzaghi's formula,A.W.Skempton's formula and J.B.Hansen's formula.Each formula is suitable for different preconditions.At present,there is no unified formula for all kinds of soil under different loads.Due to the influence of soil factors,hydrological environment,external loads and complex factors,it is extremely difficult to accurately calculate the stress of soil.Based on the analysis of the situation that the limit load value is calculated by using the above three formulas in the state of soil liquefaction,a conclusion is drawn that the ultimate load is unified when the soil is liquefied.
