The application scope of dynamic compaction is not limited to the north and south. The dynamic compaction method is to use the construction equipment to free drop the 8-40t heavy hammer from the 6-40m drop distance. Zhoushan dynamic compaction machine can impact and vibrate the foundation, so as to improve the strength of the foundation soil and reduce its compressibility.

由于其具有设备简、施工速度快、适用范围广、节约三材、经济可行、效果显著等优点，经过 20多年来的应用与发展，强夯法处理地基受到各国工程界的重视，并得以迅速推广，取得了较大的经济效益和社会效益。强夯法多年来广泛应用在建筑，水利，交通，港口和石化工程等多种工程的地基加固上.梅纳认为，强夯适用于各种类型的土壤，土壤的粒度无---.可用强夯加固由几吨重的块石组成的回填层，也可用于强夯加固含水量高于80%的粘土，几年来，国内在淤泥或淤泥质土，软塑流塑的一般粘土，饱和砂土，一般粘性土，膨胀土，黄土，高填土，碎石块石，砂土等地基上都进行了尝试和应用，有的土性得到了明显的---，有的效果甚微.

Due to its advantages of simple equipment, fast construction speed, wide application range, economical feasibility and remarkable effect, after more than 20 years' application and development, dynamic compaction method has been paid attention to by engineering circles in various countries, and has been popularized rapidly, which has achieved great economic and social benefits. The dynamic compaction method has been widely used in the foundation reinforcement of construction, water conservancy, transportation, port and petrochemical engineering for many years. According to meiner, dynamic compaction is suitable for all kinds of soil, and there is no particle size of soil. It can be used to reinforce the backfill layer composed of several tons of block stone, and can also be used to strengthen the clay with water content higher than 80% The soft plastic to flow plastic general clay, saturated sand, general cohesive soil, expansive soil, loess, high fill, gravel, sand and other foundations have been tried and applied. Some of the soil properties have been obvious, others have little effect

这就说明强夯法和其他加固方法一样，受到地基土的类别及工程性质等多种因素的影响. 我国从1978年在塘沽新港首---以后发展很快.北京，山东，上海，山西，陕西等省市相继引进，通过应用取得了不少经验，在理论研究上也取得了可喜的成绩.    强夯处理技术广泛地用于碎石土、砂性土、湿陷性黄土、人工填土、低饱和度的粉土与一般粘性土，特别令人激动的是该技术能加固处理其它方法难于加固处理的大块碎石类土，对于软土地基尤其是淤泥土地基强夯法处理需慎重对待，但若与其它方法结合可以获得较好的效果。

This shows that the dynamic compaction method, like other reinforcement methods, is affected by many factors such as the types of foundation soil and engineering properties. Since 1978, it has developed rapidly in Tanggu new port. Beijing, Shandong, Shanghai, Shanxi, Shaanxi and other provinces have successively introduced the dynamic compaction method. Through the application, we have gained a lot of experience and achieved gratifying achievements in theoretical research However, it is difficult to treat the soft soil foundation with the method of dynamic compaction, especially when it is combined with other methods such as dynamic compaction and dynamic compaction Good effect.

直到目前为止，对强夯加固效果的认识仍然停留在经验阶段。  强夯法加固机理和设计计算方法尚不成熟，有待进一步完善。随着社会经济发展和科技进步，对难度大的地基问题，较好的处理办法是综合处理，联合几种加固方法去处理。例如，对饱和度较高的淤泥和淤泥质土采用强夯法结合塑料排水板进行综合处理，或者用强夯置换法处理，各种综合方法的应用，将进一步扩大强夯法的适用土类。

Up to now, the understanding of the effect of dynamic compaction is still in the stage of experience. The reinforcement mechanism and design calculation method of dynamic compaction method are not mature, and need to be further improved. With the development of social economy and the progress of science and technology, the better way to deal with the difficult foundation problem is comprehensive treatment combined with several reinforcement methods. For example, for the silt and muddy soil with high saturation, the dynamic compaction method combined with plastic drainage plate is used for comprehensive treatment, or the dynamic compaction replacement method is used for treatment. The application of various comprehensive methods will further expand the applicable soil types of dynamic compaction method.
