Abstract


Over Soil Treatment research on the in Liupanshan region of Ningxia it as roadbed filler , to ensure the roadbed with a certain strength, stability and durability . This thesis statistics based on the Liupanshan test results , plasticity index , consistency and CBR indicators defined on through the wet soil ; doped lime water content loss after test , come to the lime dosage formula ; again by side limit compressive strength test , bearing ratio (CBR) test and resilient modulus test study using BP neural network and SPSS software to get the strength indicators and lime dosage , the degree of compaction and water content ( moisture content / regression formula of the optimum moisture content ) , combined with the relevant provisions of the foreign proposed quicklime Treatment of soil used as roadbed filler strength ( unconfined compressive strength and CBR) control recommended value ; Finally , the current degree of compaction control method analysis , taking into account the special nature of the wet soil engineering , proposed to control the porosity wet soil compaction ; while also raised the degree of compaction , CBR double the indicators control quicklime Treatment of soil compaction .
