摘要
本文在求桩的临界荷载时,考虑了柱侧土壤的弹性抗力,据此建立柱的平衡微分方程,然后用伽辽金法求解;经过一系列的演算,推导出两端固定支承时高桩和低桩的临界荷载公式及计算长度公式.两端为其它形式的支承时,也可以参照本文解题步骤和方法计算,只需采用另外的变形曲线就可以了.本文并编制了图、表,使一个很复杂的问题,可用非常方便的方法求解.
In this paper, elastic resistance of soil on the side of pile is taken into account in the solution of critical load of the pile. At first,differential equation of pile is set up, then it is solved by Galerkin method, through a series of mathematical calculations, and formulas for critical load and calculated length of high and low piles are derived. The piles are fixedly supported, and the same procedure and method may be used for piles otherwise supported, with deformation curve to be varied. In this paper, the chart used in. calculation is also given, the proposed method can change the solution to be more easily obtained
