夯坑基础技术是前苏联70年代初首先开发应用的一项地基基础新技术,其经济效益显著。针对我国地基土质的实际状况,借鉴前苏联已有经验,在陕北河庄坪基地进行了夯坑基础试验应用研究,通过试验。掌握了夯坑基础在我国湿陷性黄土地基上的实际物理力学参数、土层中夯击的影响范围和工作状态,为准确而有效地在我国应用、推广该技术提供了理论依据。
The pit foundation technology is a foundation-based new technology first developed and applied by the former Soviet Union in the early 1970s, and its economic benefits are significant. Based on the actual conditions of the ground soil in our country and using the experiences of the former Soviet Union, we conducted a study on the application of the squat pit foundation experiment at Hezhuangping Base in northern Shaanxi and passed the test. The actual physical and mechanical parameters of the pit foundation on the collapsible loess foundation in China and the scope and status of the impact in the soil layer are mastered, which provides a theoretical basis for the accurate and effective application and promotion of this technology in China.
