摘要
利用叠加原理和弹性半空间的Ｍｉｎｄｌｉｎ公式，导出了计算桩基冻胀力三维问题的积分方程。用该积分方程可计算不可压缩和可压缩的桩基冻胀力。文末给出一算例，算例表明该理论结果和实测结果吻合良好。
The integral equation for three dimensional problem of pile frost heaving force computation is derived from the principle of superposition and the Mindlin formulae in an elastic half space. The frost heaving forces of incompressible and compressible piles can be computed by this integral equation. Finally, an example is given. This example indicates that the agreements between the results of this paper and the experimental results are seen to be very good.
