Numerical Simulation of Bearing Characteristics of Bored Piles in Mudstone Based on Zoning Assignment of Soil around Piles

This study conducts a field indoor simulation test, SEM observation, and penetration test to determine the bearing capacity of dynamic driving pile in mudstone foundation. It comprehensively analyzes variation laws structure strength around piles after piling. Indeed, is significantly reduced from outside inside. Therefore, numerical should consider actual characteristics soil damage piles. The measured, scatter diagram depicting relationship between side distance produced. Then, best-fitting curve ratio simulated established by nonlinear fitting multiple curves. A method proposed damaged area parameters surrounding pile. range caused foundation determined be two times that diameter. disturbance divided into four parts on average, width each part 0.5d. results are compared conventional approach uniform parameter assignment prove rationality method.
