- 摘要:
- 随着经济发展和社会进步,在工程建设领域，地基处理技术得到了广泛应用。针对某储备基地厚度严重不均的Ⅳ级(最高级)自重湿陷性黄土和8度地震设防烈度地质的综合地基技术在工程中的应用进行了研究，通过对初勘地质资料的分析,本着安全经济、方便施工操作及监测的原则,选取初步方案,经过强夯试夯、桩基试验,综合运用多种地基处理技术,节省工程投资 4 600万元。通过实践证明,综合运用多种地基处理技术可行，而且经济、社会效益显著。
With the economic development and social progress, the foundation treatment technology has been more and more widely used. In this paper, the application of comprehensive ground technology in engineering is studied for severely uneven grade IV (highest grade) self-weight collapsible loess and 8 degree seismic fortification geology.Through the analysis of the geological data of the preliminary survey, a preliminary plan was selected based on the principle of safe and economic, convenience of construction operation and monitoring.After a series of dynamic compaction and trials compaction, based on the testing result of pile foundations, a variety of foundation treatment technologies were used. Finally, a foundation treatment plan was confirmed, and a project investment of 46 million yuan was saved.Through the practice of this project, it has been fully proved that the comprehensive use of multiple foundation treatments is not only technically feasible, but also has significant economic and social benefits.
