| 摘 要： | 机场地基处理时，提高浅部土层地基强度、减少工后剩余沉降，控制地基不均匀沉降，确保机场工后安全运行，是地基处理设计应考虑的关键问题。为了保证营口机场工程地基处理的准确性，选择有代表性的试验区进行现场试验。根据典型试验区地基现场处理数据，基于FLAC3D对试验区强夯处理进行了数值模拟研究，并把H1，H2，H3不同试验区的地基处理方法得到的数据与数值模拟计算结果对比，评价各地基处理方法的优缺点，最终确定将H2试验区的地基处理方法用于营口机场全场（跑道、联络道、站坪）大范围软基处理。

Simulation Study on the Airport Engineering Soft Foundation Treatment Method Based on FLAC3D |
| |
| Abstract: | It is a key problem for the design of foundation treatment to improve the strength of the shallow soil layer, reduce the residual settlement, control the uneven settlement of the foundation, and ensure the safe operation of the airport. In order to ensure the accuracy of the foundation treatment of Yingkou Airport project, representative test areas are usually chosen for field test. According to the on-site processing data of the foundation of typical test area, numerical simulation study is conducted based on FLAC3D dynamic compaction to the test area. According to the different H1, H2 and H3 foundation treatment methods of the test area and comparing the obtained data and numerical simulation calculation results, the advantages and disadvantages of the foundation treatment method are evaluated to finally determine to take the foundation treatment method of H2 test area to apply to large scope of foundation treatment works of Yingkou Airport (runway, linking taxiway, station site) |
