| 中文摘要:在现行规范中，由于桩基沉降估算模式的不同，压缩层厚度的确定方法也不完全相同。对这些方法进行归纳、总结，并通过具体的工程实例，对由不同估算模式确定的压缩层厚度及沉降估算结果进行探讨与分析，认为对于工程场地地质资料掌握较为翔实的情况下，压缩层厚度可采用变形比法确定，否则，宜根据应力比法确定。 |

| Abstract:In the current criterion, different models of pile foundation settlement estimation should match with different determination methods of thickness of compressed layer. These methods were summarized with engineering cases; discussion and analysis were made on the thickness of compressed layer determined by different estimation models and the result of settlement estimation. The author thought the thickness of compressed layer could be determined by deformation ratio method if geological data of construction site were detailed mastered, otherwise by stress ratio method. |
