Analysis and design of axially loaded piles in rock

Despite significant advancements in in situ test techniques,construction practices,understanding of rock joint and rock mass behaviours,and numerical analysis methods,the design of bored concrete cast-insitu piles in rock is still largely based on the assessment of bearing ***,for many of the rock conditions encountered,the bearing capacity of piles is a nebulous concept and a figment of the designer’s *** if it can be reasonably quantified,it has little,if any,significance to the performance of a pile in *** load carrying capacity of even low strength rock(in most situations)is far in excess of the strength of the structure(for example,a building column)transmitting the *** performance of a pile in rock is usually a displacement issue and is a function of rock mass stiffness rather than rock mass *** addition,poor pile performance is much more likely to result from poor construction practices than excessive displacement of the rock *** occur for footings that are undermined,or where unfavourable structure in the rock allows movement towards a free surface to ***,codes of practices,reference books and other sources of design information should focus foundation design in rock on displacement rather than strength *** investigations should measure rock mass stiffness and defect properties,as well as intact rock *** paper summarises the fundamental concepts relating to performance of piles in rock and provides a basis for displacement focused design of piles in *** also presents comments relating to how piles are modelled in widely used commercial finite element software for soil-structure interaction analysis,within the context of the back-analysis of a pile load test,and proposes recommendations for pile analysis and design.

当前采用的节理模型,如果不凭借经验,是不可能准确预测节理的剪切行为的,这已成为争论的热点。这是因为这些模型不能定量地评价节理粗糙度或尺度的重要性。介绍一种新的方法,它用分形几何来调查节理的粗糙度。这种方法已超出了简单地描述粗糙度的“症状”,而是去寻找“原因”。在该法的应用中,引入了分形几何、分维数和自相似的概念,并系统地阐述岩体节理粗糙度的统计依据和实用模型的框架。推导了分维数和起伏角与粗糙高度的标准差这两个更有用统计参数之间的重要关系。这些关系不仅为定量评价节理粗糙度提供了有用的方法,而且为解释巴顿(Barton)的经验模型(JRC-JCS)提供了基础。另外,分形模型可以为节理剪切行为的正应力作用效应和节理尺度效应提供理论模型。
