Exploratory rock probes were drilled at each pile location to design the rock socket length based on the rock quality and sloping rock conditions. The rock mass was pressure-grouted during each rock probe to improve the rock quality and fill voids in the rock.Seth K. Martin...
Large diameter (>600 mm) rock-socketed piles were used in several recent developments in Hong Kong, which involved 13 large-scale pile-load tests in various decomposed rocks. The test piles varied in length from 20 to 60 m and in diameter from 1.0 to 1.3 m. The test loads were as ...
Key words:static load test; settlement; post-grouting; end resistance; socketed depthAbstract: A series of well-designed full-scale destructive load tests were conducted on six bored piles to investigate the influence of loose debris at the pile tip on end resistance. The results show that ...

concrete ensured that the formation of a deep water bored pile of 3.0 m in diameter and 42.5 m in length would be completed within an average of 4 days.The construction effect of an actual bridge indicates that the rapid construction technique for bored pile construction is time-saving and ...
Load transfer method of the vertically loaded bored pile socketed into weak rocks was then established to capture the distribution of axial force. Moreover, a parameter study was conducted to assess the influence of the concrete-rock interface roughness, normal stiffness, and residual friction angle...

granitic and volcanic bedrocks may be taken as the sum of the frictional resistance of the rock socket and the end bearing resistance of the piles provided that the socket length used in the calculation of frictional resistance does not exceed 2 pile diameters or 6 m, whichever is the ...
This design practice significantly increases the length and cost of the pile foundation. The current study presents the bidirectional load test results on the large-diameter bored piles socketed in weak rocks at the Cua Dai bridge project, Quang Ngai province, Vietnam. The soil profile consists ...
