摘要
本文阐述了强夯法的研究现状和影响因素,然后通过对强夯机理的分析,探讨了强夯工艺在地基加固处理中的应用;结合几个工程实例中采用强夯法处理湿陷性黄土地基的具体实践,分析了用强夯法处理湿陷性黄土地基的效果,较详细地介绍了该方法的设计要点、施工工艺、检测项目、控制标准等。本文通过对有关数据的分析,对强夯法加固地基的一些问题进行了探讨,包括有效加固深度、夯击能量、夯点、合理间距及夯击遍数的确定,控制参数的选用,地基承载力的计算、消除地基土湿陷性方面的应用等。最后,对强夯处理前后效果进行了对比分析,指出了强夯法应用于湿陷性黄土地基处理的可靠性和适用性。
This paper introduces the current study situation and affecting factors of the dynamic consolidation method, then this paper is about the application of the technology for the strong tamping in reinforcing and treating the groundsill, it introduces by analyzing the principles of the strong tamping and the example in application..Combining several the actual practices of adopting the power tamp method treatment of wet and sunk loess foundation, effect using strive ramming method process has been analyzed in this paper. It gives the detailed description of its construction techniques, testing items and control standards etc. By means of relevant data, this paper probes into some problems relevant to foundation treatment by dynamic consolidation including the determination of effective strengthening depth, tamping energy level, tamping point location and rational inters pace, the selection of tamping times, the calculation of foundation bearing capacity the verification of calculating formulae, and the application of dynamic consolidation eliminating the ground. Finally, this paper gives the contrast analysis of the whole effect of the power tamp treatment, It also point out the reliability and applicability of applying the power tamp method to the loess foundation treatment.
