石灰改良黄土在定西引洮调蓄水池地基处理中的应用研究

工程技术前沿
定西引洮调蓄水池工程地基为Ⅲ-Ⅳ级湿陷性黄土,传统处理有弊端。本文聚焦石灰改良技术,选0%、3%、6%、9%、12%五种掺量试验,提“石灰改良+灰土挤密桩+BIM管控”方案并验证,本研究的主要目的是通过系统的试验和分析,确定该区域湿陷性黄土改良处理中的最优掺合料配比区间范围。研究重点考察不同掺量黄土的工程特性变化规律,涵盖压缩性、湿陷性等关键指标,为该地区及类似地质工程建设提供技术参数与施工指导。研究成果将为湿陷性黄土地基处理方案优化设计提供依据,提升工程质量与经济效益。

Motorization is the transition from non-motorized travel means (e.g., walk) to motorized travel means (e.g., car). China, as the most populous country in the world, has started the motorization process, and its results will have huge impact on the whole world in terms of transportation, energy, environment and automobile market.
