| Abstract: | Based on the technoligy of pipe sinking compacted pile,the improved shock compact gravel pile technique with vibratory drilling, outside pipe material is very significant for the effect of the fill-back soil foundation reinforce ment.This technique is very simple, low cost and high-effeciency. As result the load capacity of the combined foundation is greatly increased and has a value of promotion. |
