Experimental Study and Engineering Practice of Rammed Concrete Pile
Rammed concrete pile is the development of columnar-hammer rammed and expanded technique. Due to the twice compaction effect during installation process and high compression strength of pile shaft, rammed concrete pile has the advantages of high bearing capacity and relatively low cost. The main purpose of this paper is to study the installation procedure, the bearing behavior of rammed concrete pile and compaction effect on the surrounding soil. The indoor tests results indicate that the rammed concrete specimens take only 14 days, only half of the common concrete, to achieve the design strength, which is favorable to shorten the construction period of foundation. Additionally, the compression strength of rammed concrete is about 10 to 50 percent higher than the regular concrete with the same cement content ratio. Field tests results show that rammed concrete pile offers greater capacity than driven and cast-in-place pile. Finally a case history is introduced that further verified the compaction effect of the rammed concrete pile to the surrounding soil.
