对于桩长和桩的长径比均小于25的嵌岩桩，侧阻力随桩顶荷载的增加而增大，且在高的应力水平下平缓增长，当达到最大荷载时达到试验最大值，其嵌岩部分侧阻力从上至下依次发挥。
When pile length and the ratio about pile length to pile diameter is less than 25, side resistance is aggrandized by increasing of the load, and gently added at high stress level.
当竖向相关距离大于桩长时其变化对桩顶沉降响应方差影响不大的结论。
When the vertical correlation distance is longer than the length of pile, it has small influence on the response variance of pile top settlement.
