摘要

通过两组试验得到了素混凝土桩复合地基桩土应力分布的一些规律。在试验荷载范围内，桩土应力比随荷载的增加而增大，实测最大荷载下桩土应力比大多在9～13之间，桩的荷载分担比可达0．7以上。试验证明素混凝土桩复合地基具有承载力高、沉降变形小的优点

具有良好的应用前景。

Abstract

Some conclusions were drawn from two groups of in-site tests on concrete pile composite foundations. In the tests

it was found that the pressure under the rigid loading slab is different

in which the pressure under the center of the slab is the less and under the edge of the slab is the biggest. The pile-soil stress ratio is not a constant; it increases with the adding of the load. Most of the pile-soil ratio vary from 9 to 13 in these tests and the load that the piles share can be more than seventy percent of the whole load. It was proved that the bearing capacity of the concrete pile composite foundation is high with a little settlement

so it will be used more and more in the future.
