针对西北部分地区地表层粉砂分布不均、砂岩不易破碎、块石回填方量大、回填厚度深等问题，考虑特高压换流站工程地基处理的适用性及其成效、工期、造价等多方面因素，提出强夯地基处理方案。应用结果表明：该方法具有快速提高填土密实程度，加速填土前期固结，提高填土的物理力学性能，减少填土的后期沉降和建（构）筑物及地面设备基础的沉降等优点，可广泛应用于西北地区特高压换流站及其他大面积土石方开挖、回填及地基处理施工工程。

Aiming at the problems such as earth surface layer silt uneven distribution,difficult to broken sandstone,large earthwork of rock block backfill and deep backfill thickness in some parts of the northwest district of China,considering the adaptability,efficiency,work-period and cost of the site foundation treatment in high pressure converter station,puts forward the schemes of dynamic compaction foundation treatment. The application result shows that the method has the advantages of quickly to improve the compaction degree and preconsolidation,promote the physical and mechanical properties and reduce the late settlement of the fill soil,and reduce the foundation settlement of ground building and equipment,which can be widely applied in construction project of UHV converter station and other large earth-rock excavation,backfill and foundation treatment in the northwest district of China.
