ABSTRACT
The Press-in Method, being started with Standard Press-in (SP, press-in without installation assistance), has expanded its applicability to hard ground conditions with the development of Press-in with Augering and Rotary Cutting Press-in (RCP, press-in with the use of rotational forces onto a pile with cutting teeth on its base). Although the piles installed by these methods are usually used for retaining walls, there have recently been an increasing number of cases where SP piles and RCP piles are used for foundations. To understand the performance of these piles and establish rational design methods, it is necessary to accumulate load test results with different pile specifications and in different ground conditions. This paper reports the records of installation and the results of static vertical load tests on two piles with the outer diameter of 1000mm and the thickness of 12mm, which were installed by SP or RCP in the same site.
