摘　　要：通过室内土工试验,研究了郑西客运专线夯实水泥土桩复合地基水泥改良黄土的物理力学性质、击实特性、压缩特性及强度特性,分析了影响水泥改良黄土强度的各种因素及变化规律,对提高水泥改良黄土强度的措施提出建议.为西北地区高速铁路复合地基黄土改良方法提供参考.In soil test laboratory, the physical and mechanical properties, the compaction characteristics, the compressibility and strength characteristics of the improved loess used in the concrete piles of composite foundation on Zhengzhou-Xi＇an High-speed Railway are studied. Various factors to the strength of cement loess and variation which regulations are analyzed and the counter-measures to improve the strength of cement loess are put forward, provides reference for the study of methods to improve the concrete loess application to the high-speed rail-way construction in northwest region.
