Compared with the 1998 version,the 2012 version of Code for Pile Foundation of Harbor Engineering changes the soil depth parameters which are in the driven pile foundation parameters (qf ,qR) table,and to 50 m or 55 m above,but the parameters of many sections are not improved after deepening.From the perspective of geotechnical engineers,various types of soils in under-consolidated state,normal consolidation state and over-consolidated state are analyzed and discussed respectively.This paper discusses the necessity of the existence of under-consolidated soil (especially sludge) in this code.Based on the analysis of the difference of geotechnical engineering characteristics of various soils and combining with the comparison of a variety of normative data,the paper puts forward the following suggestions.First of all,the normal consolidation soil can increase the qf & qR values.Secondly,in the over-consolidated hard soil,(fine) sand and other fine debris soils have a greater increase in qf & qR value of the possibility.At the same time,suggestions are put forward for compiling the recommended values of qf and qR in the code.
