摘要
本文对某机场跑道试验段真空联合堆载预压法加固处理的现场试验和部分室内土工实验资料进行详尽分析。结果表明,淤泥地基在经过真空联合堆载预压法加固后各项物理力学指标均发生了显著变化,承载力大幅提高,加固效果较好。
The vacuum and surcharge preloading method is used to improve the soft soil foundation of an airport runway.The measured data in the field and laboratory geotechnical tests are studied in detail.The results show that after the mud soil foundation is improved by vacuum and surcharge preloading method,various physical and mechanical indexes of the foundation changed significantly,the bearing capacity has been greatly improved,and the reinforcement effect is good.
