| Dynamic consolidation in collapsible loess foundation treatment is one of the important methods in terating foundation, which has been widely used to treat collapsible loess foundation by virtue of its many advantages, such as convenient construction and prominently economic performance. However, due to the complexity of dynamic consolidation and many uncertain factors, the study and design on dynamic consolidation method mainly depend on project analogy and experience. Therefore, it is quite meaningful and necessary to study and analyze the affecting factors of dynamic consolidation as well as its reinforced effect to improve its application. Based on refering to lots of production in existence, much data of dynamic consolidation in collapsible loess foundation treatment are analyzed,various water content conditions fitting to dynamic consolidation are analyzed, calculation equation on sedimentation content of dynamic consolidation method in collapsible loess foundation treatment are modified by introducing sedimentation content correction factor. And many calculation methods and theories of effective consolidation depth of dynamic consolidation method are compared and analyzed; the feasibility and advantages as well as disadvantages of various algorithms are indicated. Considering influencing factors of dynamic consolidation, single-damp subsidence, soil water content as well as void ratio, experiential computation equation on effective consolidation depth and sedimentation content of dynamic consolidation in collapsible loess foundation treatment is given by using multivariate linearity regression analysis method. The feasibility of dynamic consolidation method in collapsible loess foundation treatment is validated by computing and analyzing engineering examples.
