- Abstract
In modern times, with the rise of high buildings, the timber piles were replaced by steel piles, precast concrete piles and various composition foundation, the main reason is that the soft ground improved with timber piles has the weakness of low bearing capacity and large post construction settlement. To overcome the weakness of the traditional pine-pile technology and expand its application in engineering practice, the drained-timber pile: A new timber pile technology was developed. To verify the feasiblity and evaluated the effectiveness of the drained-timber pile technology, four types of laboratory soil-column consolidation tests were performed. The test results revealed that under the same loading and consolidation time, the radial consolidation of the drained-timber rod has a domiant contribution to the total degree of consolidation, the drained geotextle layer of drained-timber rod can obviously increase the degree of consolidation comparing with traditional timber rod. It can be expected that the new timber pile technique has a good application prospect in soft ground improvement for medium-small size hydraulic structures.
