Study On The Bearing Capacity And Deformation Analysis Of Reinforced Soil Foundation

In this paper, on the basis of the conclution of the analysis theories and calculation methods, using the FLM numerical simulation method, combined with the reinforced soil foundation of the track beam of one port area which used Longmen crane,a systematic ananlysis of reinforced soil foundation is studied, and the main results are as follows:(1)On the considerations of the roles of stress proliferation, the vertical component of the pulling force, and the horizontal component which caused the lateral pressure and deep-base effect of the reinforced soil foundation, proposed the Amended formula of calculating the bearing capacity of reinforced foundation.(2)Through the FLM numerical simulation, a series of comparison of the calculation are done.The result show that, the length and the layers of the reinforced-material have an obvious impact on the bearing capacity and the settlement of the reinforced soil foundation. With the increase of the length of the reinforced-material, there is a quick increase of the bearing capacity, and then the increase is weaked after it had reached an optimum value. With the increase of the length of the reinforced-materials, there is an obvious reduction in settlement results, and then there is a little changement after it had reached an optimum value. With the increase of the layers of the reinforced-material, there is a quick increase of the bearing capacity, and then the increase weaked after it had reached an optimum value, then reincrease the layer, have little impact on the increase of the bearing capacity. The settlement decreased with the increase of the layers of the reinforced-materials, after it had reached an optimum value, reincrease the layer, have little impact on the settlement results.(3)Through a variety comparative analysis of the calculation methods, the results of the Amended formula of calculating the bearing capacity and the numerical simulation results of bearing capacity are nearly equal to each other. The settlement calculation results of HuangWenxi's method'and the numerical simulation results are nearly equal to each other. The Amended method which proposed in this paper and the numerical simulation method have practical engineering value.
