The base is divided into finite block element. So, the stress and load that this system divided can be calculated. Combining analyzing Morrow Point dam on Colorado River with this method, the rationality of it is validated.

• 应用上述方法，结合Morrow Point双曲拱坝，计算了该坝的分载与径向位移，其成果合理，验证了本文建立的坝体虚拟弹性地基梁与坝基块体有限元组合的拱坝分载法的合理性，且满足工程精度的要求，有一定的实用价值。
