黄土软基具有饱和度高、强度低、无湿陷性的特征。本文在归纳总结水泥搅拌桩分类与特点的基础上,以甘肃省兰州至海石湾高速公路黄土软基路段的处治为工程实例,分析了土工格室加筋配合水泥搅拌桩综合处治技术在软基路段的应用。通过现场静载荷试验,得出地基土层未达到极限状态,试验结果理想,并对其原因进行了分析研究,为今后在同类地区进行地基工程的处治提供借鉴。 Loess soft foundation with high saturation, low strength, non-collapsible characteristics. Based on the classification and characteristics of cement mixing piles, taking the treatment of loess soft ground section of Lanzhou-Hai-Shiwan Expressway in Gansu Province as an example, this paper analyzes the effects of geogrid reinforcement and cement mixing pile comprehensive treatment technology in soft Application of base section. Through the static load test in the field, it is concluded that the foundation soil does not reach the limit state and the test result is satisfactory. The reason is analyzed and studied, which provides reference for the future treatment of foundation engineering in similar areas.
