一、前言 基土的水泥灌浆法是土壤人工加固方法的一种。人工加固的目的在于提高基土强变,或增加其不透水性。在砂土和礫石工中压入水泥灰浆,使土壤顆粒被水泥浆所粘結和空隙被填充。通过这种方法使松散的和多孔性的土壤变为水泥粘結的坚实的整体。灌浆法很適用于有裂縫的岩石类、大块碎石类及粗粒砂土,而对於細顆粒土壤几乎沒有效果。 I. INTRODUCTION The cement grouting method in the ground soil is a kind of soil artificial reinforcement method. The purpose of artificial reinforcement is to increase the strength of the base soil or to increase its impermeability. In sand and gravel workers, cement mortar is pressed in so that the soil particles are bound by the cement slurry and the voids are filled. By this method, the loose and porous soil becomes a solid whole of the cement bond. The grouting method is very suitable for cracked rocks, large gravels and coarse sand, but it has little effect on fine-grained soils.
