一、引言水平力作用下的桩基计算,通常按其实际状态分为弹性桩(弹性基础)和刚性桩(刚性基础)两种情况。这种分类纯粹是从简化计算的角度来考虑的。当按此分类后,对于刚性桩的计算将可能减少许多繁杂的计算工作而仍然取得滿足实用要求的近似结果。无量纲解法可以通过简捷的运算获得精确解,在用于计算弹性桩时,这种优点尤其明显,以致使弹性桩的计算并不比刚性桩的计算复杂很多。这样似乎并无突出的必要来区分弹性桩和刚性桩。但是 I. INTRODUCTION The calculation of pile foundation under the action of horizontal force is usually divided into two cases: elastic pile (elastic foundation) and rigid pile (rigid foundation) according to its actual state. This classification is purely from the perspective of simplifying the calculation. When classified according to this classification, the calculation of rigid piles will likely reduce many of the complicated calculations while still obtaining approximate results that meet practical requirements. The dimensionless solution yields an exact solution with straightforward calculations. This is especially true when used to calculate elastic piles, so that the calculation of elastic piles is no more complicated than the calculation of rigid piles. There seems to be no obvious need to distinguish between elastic and rigid piles. but
