Pile sockets involved rocks with different strengths such as marl, limestone, gypsum, and diabase. The pile response during static loading depended on the rock strength, the length of the socket in the rock, and the length of the pile in the soil. In this paper, an analytical model is ...
of pile tip is;(3) the pile tip load-sharing ratio decreases with the increase of rock-socketed proportion.This method takes into account the settlement requirements of upper structure as well as the load-sharing ratio of pile tip,so the rock-socket length can be determined comprehensively ...
A series of rock socketed model pile load tests was carried out using the indigenously developed loading frame and set-up. Two Aluminum tube piles having outer diameter of 60 and 80 mm were used in the investigations. Different length-to-diameter ratios were considered by changing length of ...
The piles were observed to behave in an elastic manner when tested to normal working loads. Much of the applied loads was transferred through the pile shaft especially when the socket length was in excess of twice the pile diameter, while relatively little load was transferred to the pile base...
The numerical results are discussed in terms of the lateral load–deflection relationships and bending moments along the length of the pile with reference to pile head fixity conditions and rock socket lengths, which are of prime interest to designers. The limiting rock socket lengths for achieving...
of surrounding soil,on the buckling of the pile shaft,the most general exponential distribution of subgrade reaction coefficient is assumed and the total potential energy equation of the pile-soil system is set up based on the simplified elastic beam model.Then,solutions for the buckling length ...

5) rock-socketed length 嵌岩深度 1. Using the FLAC3D algorithm based on explicit finite difference method,the effect of pile settlement by pile length,material of pile,the property of rock at the bottom of pile tip and rock-socketed length is simulated and analyzed,and the result ...
In this paper ,some of the developments about side resistance of socketed pile in weak rock are presented. 软岩嵌岩桩作为一种基础形式 ,目前国内研究较少。 2) socketed pile 嵌岩桩 1. Analyze bearing characteristics of socketed pile with new grey relationship theory model; 用新的灰关联理...
设计参数载荷试验标准桩基变形On basis of the design of rock socketed pile, some problems are discussed, concerning the design method, design standard, design parameter and the standard on loading test of pile. The study results show that the design method should be based on the bearing behaviors...
