The Application Of Compaction Pile In Collapsible Loess Regions

First, the thesis briefly produces the designing basic principle on collapsible loess regions instruction project on the basis of learning and digesting the formers research result, and summarizing electric power project practice for many years, connected with the actual GBJ25-90 of Code for Building Construction in Collapsible Loess Regions.Second, it combines the loess collapse assessment with the selection of the common ways of ground treatment, and begins with assessing the loess collapse accurately to analyze how to choose the fit ways of ground treatment according to the assessment result.Finally, taking the compaction pile technique of a certain power station for example, it points out some attentive questions and probable ground treatment effects in the ways of the design, construction and examination of lime-soil compaction pile and DDC pile. Meanwhile, it compares and analyzes the differences of technology and ground treatment effects between the two compaction piles from which my thought and orientation opinion are summed up in order to be promoted in the application of the project.
