| 针对青海地区盐渍土特殊工程地质性质,本文就其地基处理方法进行了较为深入细致的论证和研究。通常情况下,强夯、灰土或易夯实的非盐渍土回填法等地基处理方式是经济可行的。但在青海盐渍土地区,事实证明这些地基处理方式往往是行不通的。本文通过几个失败案例的分析,引申出几个成功的地基处理案例。事实证明,当按规范、规程所纳入的方法不能达到理想效果时,会催生出一些新的地基处理思路,从而指导我们不断进步。本文论述的毛细水隔断法、各类桩基及复合地基方案、裹体桩应力缓释法、低热微膨胀水泥的应用等地基处理方法,在青海地区盐渍土地基处理工程中取得了非常好的效果。 |
| 英文摘要: |
| According to the special engineering Geological properties of saline soil in Qinghai area, the method of foundation treatment is demonstrated and studied in detail. Under normal circumstances, it is economical and feasible to treat foundation such as strong compaction, grey soil or non-saline soil backfill method that is easy to compaction. However, in Qinghai salt-bearing soil areas, it has been proved that these ground treatment methods are often not feasible. Through the analysis of several failure cases, several successful foundation treatment cases are derived. Facts have proved that when the methods included in the rules and regulations do not achieve the desired results, they will lead to new ground treatment ideas, which will guide us to continuous progress. The method of capillary water separation, various kinds of pile foundation and composite foundation scheme, stress relief method of wrapped pile, application of low-heat micro-expansion cement and other foundation treatment methods discussed in this paper have achieved very good results in the saline soil foundation treatment project in Qinghai. Worth promoting and applying. |
