摘要
通过分析塑料排水带固结处理深厚软土地基的效果和设计有关的问题,及非理想井固结理论分析估算,认为塑料排水带插设间距是影响预压期长短和固结度增长的关键因素,合理布置间距可使完工期地基土平均固结度达80%以上,插设深度主要影响工后沉降的大小.
This paper analyses the effects and problems concerning the application of plastic drain to the consolidation of soft soil foundation. After the analysis and calculation with non-ideal consolidation theory, we arrive at the conclusion that the space between plastic drains is the vital factor that affects the precompression and consolidation. Reasonable spacing can ensure that the consolidation rate is over 80 percent when the project is finished. The depth of the plastic drains is related to the settlement of the soil foundation.
