国外某高孔隙比地基土工程特性研究

Research on Civil Engineering Characteristic of High Hole Ratio Foundation in Overseas

国外某电厂分布有高孔隙比、高压缩性粘性土,这类粘土虽然承载力较高,但在承受建筑物荷载时会产生较大压缩变形,从而影响上部结构稳定性。本文通过对该工程地基土的岩土工程勘测研究分析,得出该高孔隙比粘土的岩土工程特性,虽其承载性能较好,但不能作为沉降敏感建筑物的天然浅基持力层。本文研究结论可以为该地区进行其它工程建设提供参考。

The clay with high void ratio is founded in the site, although its bearing capacity is good, the deformation under the building load is still large because of its high void ratio. In this paper, characteristics of such kind of clay are studied through the geotechnical investigation. The result shows that this type of clay may cause large deformation, it can not be regarded as the bearing stratum to the building which is sensible to the settlement. The conclusion in this paper can be used for references to other engineering.
