Performance Study and Numerical Calculation for Horizontal Bearing of Grouting Piles in Silty Soil Foundation

Because of the complexity of pile-soil interaction under the effect of horizontal load, the calculation theory and method for horizontal bearing pile are not perfect, so further study shall be conducted. Based on the basic field test of long elastic pile in a port project, the construction effect of cement injection pile has been evaluated according to the testing results in this paper. ABAQUS has been used for three-dimensional simulation calculation of the single pile in the testing area; smeared cracking model has been used for simulating the endurance of concrete; embedded element has been used to simulate the reinforcement bar in concrete. The inner force distribution in every elevation of pile has been calculated, and then compared with testing value and the results suggest that the precision of numerical calculation can meet the engineering requirements.
