Application of Short-Static Driven Piles for High-Rise Building in Nanning

Abstract

In Nanning basin, because of the peculiar relief and stratum model, the bearing support soil layers for pile foundation of high-rise buildings generally is gravel layer or mudstone layers or sandstone layers. On first or second terrace in basin, gravel layer is most chose as the bearing stratum for pile foundation of high-rise buildings. Static driven piles are commonly used in Nanning, because they have advantages of fast construction, high bearing capacity and noiseless despite costly. In this paper, the actual test data of a 32-stories apartment building of a college in Nanning has been consider- ed in detail. According to the present situation of project operations, the test results show that the piles which length is less than 6m can fully meet the design requirements. This project is a successful example.
