The prestressed hammer driven piles aided by water jetting were used as the substructure of a wharf, and transverse cracks were observed in the bodies of the five test piles. 摘要某碼頭工程下部結構采用預應力水沖錘擊樁，試樁過(guò)程中發(fā)現，在貫入度較大的情況下樁身多處產(chǎn)生橫向裂縫，使樁尖無(wú)法達到設計標高。
This paper analysed the different exertion properties of socket piles with different rock strength at the bottom of each pile. 摘要通過(guò)對工程試樁資料的分析，闡述樁端支承條件不同時(shí)端阻力發(fā)揮性狀的差異。
