Abstract


The presence of organic matter will cause the high plasticity of the soil , high shrinkability , high compression resistance , low permeability and low intensity . Higher organic matter content of the soil generally in need of reinforcement, in order to meet engineering requirements . By laboratory experiments , preparation of different organic matter content of soil organic matter and clay of a construction site in Hangzhou , liquid and plastic limits , to discuss the relationship between the organic matter content of the soil liquid and plastic limit , plasticity index . Add organic matter on a construction site in Hangzhou, silty clay , cement reinforced with cement the GR03 reinforcement comparative test , the main discussion GR03 ash solidified soil organic matter content , cement content , water-cement ratio , age , and other factors unconfined anti- pressure strength . Solidified soil triaxial consolidated undrained test to discuss the form of solidified soil destruction and its stress -strain relationship . In the test range , the main conclusions are : 1 . Plastic limit with organic matter content available linear function of simulation; relationship is exponential function simulation of liquid limit , and organic matter content . 2. The cement reinforcement tests showed that : curing the strength of the soil with organic matter content increase was exponential decay with increasing cement content was increased S-type relationship with the water-cement ratio can be used parabolic analog simulation of hyperbolic functions available with the age of the relationship . 3. Cement reinforcement GR03 tests showed : GR03 can improve the strength of the stabilized soil , the solidified soil strength decays exponentially with increasing organic matter content , available power function simulation cement content relationship , relationship with the water-cement ratio can be used hyperbolic function analog age hyperbolic functions available analog . 4. The stress and strain of stabilized soil available exponential function simulation .
