“…According to the statistics of field tests conducted by Ma [3], ram-compacted piles with vibrating gravel base is capable to reduce settlement of roadbed in soft soil areas efficiently. What is more, a series of research by Chen [4] indicated that the improvement of properties of adjacent soil surrounding piles can increase ultimate bearing capacity of foundation apparently. Currently, ram-compacted piles with vibrating gravel base is on trial in Ningxia Hui Autonomous Region of P.R.China where collapsible loess is widely distributed.…”

Abstract. Ram-compacted piles with vibrating gravel base is a simple method of foundation treatment which was applied to engineering in soft soil areas initially with which soil surrounding can be compacted by the impact of hammer transitted by gravel. Relatively low cost and ordinary construction technique have made it begin to take shape in general industrial and civil engineering. However, a mature frame of reference about the application of ram-compacted piles with vibrating gravel base in collapsible loess foundation especially vertical bearing capacity is still under research. This paper proposes a theoretical hypothesis of pile-soil model based on Mohr-Coulomb Model. The results of finite element analysis of ram-compacted piles with vibrating gravel base are used to verify that its vertical bearing capacity is up to standard generally while stress concentration on the uneven boundary of concrete and gravel base can not be ignored as well.
