Abstract

In European Union, the basic geotechnical code "EUROCODE 7 - Geotechnical design, Part 1 - General rules" (EC7-1) has been finished and its National Annexes have been drafted. The designs according to both EC7-1 and the Czech basic standard ČSN 73 0031 “Structural reliability – Basic requirements for design” are based on the Limit State Design theory. However, there is a principal difference between the inputs according to EC7-1 and the inputs according to ČSN 73 0031. In general, the input difference results in too conservative (ineffective) designs according to EC7-1 and more effective (more optimistic) designs according to ČSN. Due to these differences analyses of slopes, shallow foundations and earth pressure concepts have been carried out and an analysis of pile design appears necessary, too. The Paper shows briefly the history and development of the Ultimate Limit State Design of bored piles. Attention focuses on a comparative analysis of the tabular design values and the results of numerical analysis and their suitability for the Czech National Annex of EC7-1. The analysis results are compared with tabular design values of the relevant Czech standard.

History of Ultimate Limit State of Bored Piles

Arlington, Virginia

In European Union, the basic geotechnical code "EUROCODE 7 - Geotechnical design, Part 1 - General rules" (EC7-1) has been finished and its National Annexes have been drafted. The designs according to both EC7-1 and the Czech basic standard ČSN 73 0031 “Structural reliability – Basic requirements for design” are based on the Limit State Design theory. However, there is a principal difference between the inputs according to EC7-1 and the inputs according to ČSN 73 0031. In general, the input difference results in too conservative (ineffective) designs according to EC7-1 and more effective (more optimistic) designs according to ČSN. Due to these differences analyses of slopes, shallow foundations and earth pressure concepts have been carried out and an analysis of pile design appears necessary, too.
