Rock-socketed Pile Bearing Capacity And Settlement Analysis Research

Rock-socketed piles is refers to the part or all pile embedded in rocks of pilefoundation. Compared with other types of piles, pile embedded has many obviousadvantages of it make full use of the bearing capacity of rock, so as to improve thebearing capacity of single pile because it has its high bearing capacity, small settlementand seismic performance is good wait for a lot of advantages as Bridges, high-risebuildings, such as heavy-duty workshop structure of a kind of important foundationforms, has been widely used in practical engineering.First of all, this article refer to the domestic and foreign literature about themechanism of rock-socketed pile bearing, understand the research status at home andabroad; Second, as the starting point from the pile load transfer mechanism, discussedthe rock-socketed pile of rock-socketed pile with the similarities and differences andtheir respective characteristics of load transfer, and analyzes the lateral resistance of pileto soil, and rock pile side resistance and end resistance of the working mechanism andthe main influencing factors; Finally, in detail elaborated the current main method forcalculating the bearing capacity and settlement of rock-socketed pile, and summarizestheir respective advantages and disadvantages.In addition, in this paper, through the field measured data of guangdong andanalysis of the stress characteristics of rock-socketed piles for short, long rock-socketedpile rock-socketed piles, the stress of the long rock-socketed pile character difference,working mechanism of rock-socketed pile are obtained and the law of mechanicalresponse. And on this basis, the pile top settlement of rock-socketed pile are introduced,the characteristics of pile body compression curve. Through the settlement of pile topand pile tip resistance and pile side resistance theory relations to analyze the influencefactors of rock-socketed pile settlement, according to the characteristics of the easternguangdong, Pesll rock-socketed pile bearing on the subsidence calculation method ofrock-socketed pile correction formula of calculate the settlement of single pile, and thecalculated values and measured values comparison and analysis, validate its rationality.
