The Test Of Soil Property And Numerical Simulation Of Bearing Capacity For Chemical Corrosion Foundation

In general,the environmental pollution evaluation and control are mainly considering the impact on the environment,the control aim are air,water resource and food etc.However,view from the soil mechanics and engineering,the corrosion effect of contamination in the soil will weaken the soil mechanical properties and foundation bearing capacity,which do harm to the safety on construction engineering.The laboratory tests regarding mechanical property of erosion soil were carried out in this study,including the tests of maximal dry density and liquid plasticlimitation, corresponding to the conditions of different concentration of sulfuric acid solution and sodium chloride solution,respectively.So as to explore how the erosion states affect the dry density and liquid plasticlimitation of soil.The test results show that the erosion solution had significant effect to soil,and the bigger the concentration is,the more evident the influence is.The conventional analytical method to solve bearing capacity problem is based on very simplified conditions,which has limitation for foundation with complex condition, especially erosion soil condition.Therefore,the thesis proposed a numerical test method for bearing capacity of erosion foundation based on Fast Lagrange Analysis numerical simulation and utmost analysis theory.The method has good adaptability because it fully utilizes the ability of numerical simulation.The results of engineering calculation show that this method can get satisfied calculation results and provide visual destroying process expediently.The erosion soil research gets more and more attention,so the laboratory test results and the numerical test method proposed for erosion soil foundation capability in this thesis has active significance in this field.
