The Loess Foundation Compacting Mechanism And Engineering Application Research

The related lime-soil compaction pile soil compaction effect between the numerous studies, consider under the influence of pile soil moisture distribution density between the research field.This paper respectively from the relatively static load and the dynamic load is analyzed from two angles to consider, under the influence of pile soil moisture content between density field distributions made related research.Through the experiment and simulation lime-soil compaction pile compacting process, different moisture measuring the density of pile soil field distributions. Experimental results reveal the moisture content is larger, the impact compaction scope; Along the radial distance, this paper test initial dry density 135 cases with moisture content, dry density variation rules of basic into two phases area, (0 to 1.0) d range, water content, the greater the compaction added after the smaller dry density, 1.0 d the outside range, water content, compacting added after the dry density.Through further ABAQUS software numerical analysis concluded that consider static loading the pile soil moisture influence density field distribution rule. For this study, the initial dry density 1.35 15% to 23% in moisture content, radial distance, will density field is divided into three regions, range of (0 to 1.0) d, water content, greater compaction added after the smaller, dry density for moisture influence reduce area; range of (1.0-1.2) d , water content of dry density change of big impact for moisture influence unchanged area; 1.2 d, the greater the outside range, water content after compaction, the greater the dry density for water added up area. Through numerical analysis concluded that ABAQUS software considerations when hydrodynamic load pile soil moisture influence distribution density field, and reveals the dynamic loading than static load cases consider water content of dry density effect of variation, water content, hydrodynamic load equals the compacting radius is lesser. Moisture influence reduce zone when considering dynamic loading is bigger, and dry density increases zone moisture influence when considering static load dry density is bigger.
